Similar triangles Similar triangles, similarity criteria Exercises. The names of the big numbers differ depending where you live. The places are grouped by thousands in America, or France, by millions in Great Britain not alwaysGermany variabpes Spain.

We will read the numbers in our own way although we must be capable of recognize the correct meaning of numbers when the information comes to us from USA, for example. Decimals Decimal fractions are said with each figure separate. Each place value has a value that is one tenth of the value to the immediate left of it. We will see all this more detailed in chapter 2. We will see this more detailed in chapters 3 and 5 Exercise 1 a Write in words the following numbers as in exercisf example.

Especial cases: Squares and lcass powers of two and three 32 is read as: - Three squared - Three to the power of two. Positive integers are all the whole numbers greater variablles zero: 1, 2, 3, 4, 5, Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, …. The Number Line The number line is a line labelled with the integers in increasing order from left to right, that extends in both directions:.

For any two different places on the number line, the integer on the right pair of linear equations in two variables class 10 notes exercise 3.2 greater than the integer on the left. If the number is positive, the absolute value is the same number. If the number is negative, the absolute value is the opposite.

The absolute value of pair of linear equations in two variables class 10 notes exercise 3.2 number is always a positive number or zero. We specify the absolute value of a number n by how does a data bank work n in between two vertical bars: n. Exercise 3 Plot on the number line and after order synonym easy read from less to great.

When adding integers with the same sign: We add their absolute values, and give the result the same sign. With the opposite signs:. We take their absolute values, subtract the smaller from the larger, and give the result the sign of the integer with the larger absolute value. Subtracting an integer is the same as adding the opposite. Lienar convert the subtracted integer to its opposite, and add the two integers.

The result of subtracting two integers could be positive or negative. Exercise 4 Calculate operating first the expressions into brackets. If one or both of the integers is 0, the product is 0. To multiply any number of integers: notess. Count the number of negative numbers in the product. Take the product of their absolute values. If the number of negative integers counted in step 1 is even, the product is just the product from step 2 positive.

If the number of negative integers is odd, the product is the opposite of the product in step 2 give the product in step 2 a negative sign. Then do multiplications and divisions in the order they appear. Then do additions and subtractions in the order they occur Easy way to remember them. The products of a number with the natural numbers 1, 2, 3, 4, 5, The multiples of a number are obtained by multiplying the number by each of the natural numbers. If a number can be expressed as a product of two whole numbers, then the whole numbers are called factors of that number.

Exercise 10 Write down four consecutive multiples of: a 7 greater than b 15 greater liear c 9 greater than Exercise 14 Find out the missing figure so the number there can be more than one answer a 3[ ]1 is a multiple of 3 b 57[ ] is a multiple of 2 c 23[ ] is a multiple of 5 d 52[ ]3 is a multiple of 11 Exercise 15 Factorise: a Example: Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, … Multiples of 3 are pakr, 6, 9, 12, 15, 18, … So, common multiples of 2 and 3 are 6, 12, 18, ….

Lowest common multiple The smallest common multiple of two or more numbers is called the lowest common multiple LCM. Liner Multiples of 8 are 8, 16, 24, 32, … Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, … LCM of 3 and 8 is 24 In general there are two methods for finding the lowest common multiple LCM of two or more numbers:.

Method I For small numbers List the multiples of the largest number and stop when you find a multiple of the other number. This is the LCM. To find the lowest common multiple LCM of two or more higher numbers: - Find the prime factor decomposition. Example: Find the lowest common multiple of 18 and To find the Highest Common Factor of two or more higher numbers: - Find the prime factor decomposition.

Exercise 17 We want to distribute l of water in bottles which all have the same capacity. Find out all the different solutions. Indicate how many bottles we get in each case and the capacity of each one. Exercise 18 Sandra can pack her books in boxes of 5, why is my phone not showing network and 9.

She has less than books. How many books has she got? Exercise 19 We want to divide a rectangle of cm by 90 cm into equal squares. Find out the pair of linear equations in two variables class 10 notes exercise 3.2 of the biggest square in cm. Calculate how many squares we get. Exercise 20 Iberia clsas a flight from Madrid to Ankara every 8 days, British Airways one every 12 days and Easy Jet one every 6 days; one day all three have a flight to Ankara.

After how many days will the three flights coincide again? Exercise 21 A group of students can be organized in lines of 5, 4 and 3 claas and there are less than students. How many are there? Exercise 22 On a Christmas tree, there are two strings of lights, red lights flash every 24 seconds and green lights every 36 seconds. They start flashing simultaneously when we connect the tree.

When will they flash together again? So 7 is seventy units 5 is five units 3 is three tenths of a unit 2 two hundredths of the unit 4 is four thousandths of a unit And we continue like that if there are more digits. This is the decimal system that is commonly use nowadays except, sometimes, for time and linaer. Repeating decimals: There is a group of digits that are repeated forever. Examples If we divide 4 by 3 we get 1. The group of repeated decimal digits is called the period on the first case our period is 3 on the second case the period is Irrational numbers: They have an unlimited varibales of decimal digits but there is not any period.

For example representing the numbers 2. Example between 2. Example 1. Find two numbers between each pair of decimal numbers a 2. Sexagesimal system is more frequently used; on this system every unit is divided into 60 equal parts to get the subunit. For the angles the unit is the degree. The subunits of the degree are the minute and the second. For time the unit as you know is the hour and is divided into minutes and seconds with the same relationship they have on the angles.

A period of time is expressed as 3 h 5 min 3 s for example. We need to be able to operate in this system using these two magnitudes. The remainder is in seconds. At what time does it finish its training? Running I need the double of the time and using my car I need the third. How long does it take to oc going from A to B running and how equagions driving?

Remember: 1 Fractions A fraction is a number that expresses part of a unit or a part of a quantity. Fractions are written in the form. The denominator is the number, clxss indicates how many parts the unit is divided into. The numerator of a fraction indicates how many equal parts of the unit are taken. The rule is: The value of a fraction does not change multiplying or dividing its numerator and denominator by the same number The process of dividing numerator and denominator by the same number is called reduction 12 3 is equivalent tobecause we have divided both the numerator and the 20 5 denominator by 4.

The fractions. We can test if two fractions examples of effects of air pollution equivalent by cross-multiplying their numerators and denominators. This is also called taking the cross-product. Since the cross-products are the same, the fractions are equivalent.

There are two methods of reducing a fraction to the lowest terms.
