What is the missing number in 7 10 = 20 ?

Given, 7 10 = 20 . We know that, if two or more fractions have the same value, they are called equivalent or equal fractions. Also, the value of a fraction does not change if its numerator and denominator are both multiplied and divided by the same non-zero number. For example, 4 7 and 4 × 2 7 × 2 = 8 14 are equivalent fractions. Similarly, in the given problem, 7 10 can also be written as, 7 × 2 10 × 2 = 14 20 Here, 7 10 = 14 20 are equivalent fractions. Hence, the missing number is 14 .

Of 5 13 and 10 13 , which is greater?

The given fractions are, 5 13 and 10 13 . Comparing fractions means comparing their values to find out which of them is the greater or smaller fraction. Now, we know that, if two fractions have the same denominator, the greater fraction has the greater numerator. Here, in the given fractions, both the fractions have the same denominator. That is 13 . Now, clearly, 10 > 5 Hence, 10 13 > 5 13

Write three equivalent fractions of 4 9 .

Given: 4 9 A fraction is a part of a whole. The number on the top is a numerator, which shows how many equal parts of the whole are being dealt with. The number on the bottom is a denominator, which shows the total number of equal parts that the whole has been divided into. To find an equivalent fraction, we have to either multiply or divide both the numerator and denominator by the same number. 4 9 × 2 2 = 8 18 , 4 9 × 3 3 = 12 27 , 4 9 × 4 4 = 16 36 Hence, three equivalent fractions of 4 9 are 8 18 , 12 27 , 16 36 .
