#### Equivalent Fractions

Two or more fractions which indicate the same fractional number are called equivalent fractions.

that 1/2, 2/4, 4/8 and are equivalent fractions.

##### Write four fractions equivalent to 5/7.

5/7 = 5/7 x 2/2 = 5/7 x 3/3 = 5/7 x 4/4

So, 5/7 = 10/14 = 15/21 = 20/28

Hence, four fractions equivalent to 5/7 are 10/14,1 5/21, 20/28 and 25/35

##### Fractions in The Lowest Term

A fraction is said to be in its lowest term (or in simplest form), if the HCF of numerator and denominator is 1.

For example, fractions 1/3, ¾, 5/19 and 8/17 are all in their lowest terms.

To express a fraction in its lowest term, we divide the numerator and denominator by their HCF.

##### Reduce to the simplest form: (i) 9/21, (ii) 32/68

(i) Here, numerator is 9 and denominator is 21.

Let us find the HCF of 9 and 21.

Factors of 9 are 1, 3 and 9.

Factors of 21 are 1, 3, 7 and 21.

Common factors of 9 and 21 are 1 and 3.

So, HCF of 9 and 21 is 3.

Thus, (9/3)/ (21/3) = 3/7

Thus, 3/7 is the simplest form or the lowest term of 9/21.

(ii) Here, numerator is 32 and denominator is 68. Let us find the HCF of 32 and 68

Factors of 32 are 2, 2, 2, 2, 2 and Factors of 68 are 2, 2, 17

Hence HCF of 32 and 68 is 4

Thus (32/4)/(68/4) = 8/17

Hence, 8/17 is the simplest form or the lowest term of 32/68.

##### What do you mean by equivalent fraction?

in this question you have to divide both parts of the fraction by the same number to get the equivalent fraction.

##### What are some examples of equivalent fractions?

Equivalent fractions are the fractions that have different numerator and denominator but are equal to the same value. For example, 2/4 and 3/6 both are equal to ½.

##### How do you solve equivalent fractions?

You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount. You only multiply or divide, never add or subtract, to get an equivalent fraction. Only divide when the top and bottom stay as whole numbers.
