Question

Ranjit gave away 2/9this stamps and had 21stamps left.hoe many stamps did he give away?

Answer 1

Given:

Fraction of stamps given = 2/9

Total stamps left = 21

To find:

Total number of stamps given.

Solution:

Let the total number of stamps be x.

We know that a whole in a fraction is 1.

Therefore, if 2/9 of total stamps are given, then,

Fraction of stamps left = 1 - 2/9

=> Fraction of stamps left = 7/9

According to the question, total stamps left is 21

Therefore,

(7/9) of x is 21

(7/9)x = 21

7x/9 = 21

x = 21*9/7

x = 27

Therefore,

Total number of stamps are 27, then,

Number of stamps given = Total number of stamps - Number of stamps left

=> Number of stamps given = 27 - 21 = 6

Hence, total number of stamps given is 6.
