Question 5.

Find two equivalent fractions for each of the following fractions.

Solution:

Like fractions and unlike fractions

Fractions such as \(\frac{1}{7}, \frac{4}{7}, \frac{6}{7}\) whose denominators are equal, are called ‘like fractions’.

Fractions such as \(\frac{1}{3}, \frac{4}{8}, \frac{9}{11}\) which have different denominators are called unlike fractions’.

Converting unlike fractions into like fractions

Example (1) Convert 5/6 and 7/9 into like fractions.

Here, we must find a common multiple for the numbers 6 and 9.

Multiples of 6 : 6, 12, 18, 24, 30, 36, ……..

Multiples of 9 : 9, 18, 27, 36, 45 ……..

Here, the number 18 is a multiple of both 6 and 9. So, let us make 18 the denominator of both fractions.

Thus, 15/18 and 1418 are like fractions, respectively equivalent to 5/6 and 7/9.

Here, 18 is a multiple of both 6 and 9. We could also choose numbers like 36 and 54 as the common denominators.

Example (2) Convert 4/8 and 5/16 into like fractions.

As 16 is twice 8, it is easy to make 16 the common denominator.

\(\frac{4}{8}=\frac{4 \times 2}{8 \times 2}=\frac{8}{16}\) Thus, 8/16 and 5/16 are the required like fractions.

Example (3) Find a common denominator for 4/7 and 3/4.

The number 28 is a multiple of both 7 and 4. So, make 28 the common denominator. . Therefore, 16/28 and 21/28 are the required like fractions.
