Question

a bag of sweets contains mints and toffees. There are 21 mints and a quarter of the sweets are toffees. Calculate the total number of sweets

Answer 1

There are 28 sweets in total.

Explanation:

x = total number of sweets = 4/4

toffees = 1/4 or a quarter

4/4 - 1/4 = 3/4

3/4 of x = 21 mints

3/4*x = 24

3x = 21*4

x = 21*4/3

x = 28

Hope this helps.
