Xavier had some apricot scones and strawberry scones. He gave away 128 scones to his sister. 25% of them were apricot scones and the rest were strawberry scones.

1. How many strawberry scones did he give his sister?
2. Xavier gave some apricot scones to his brother. ⁵₇ of all the scones he gave away to his sister and his brother were apricot scones. How many apricot scones did he give his brother?

(a)
Percentage of strawberry scones
= 100% - 25%
= 75%

Number of strawberry scones that Xavier gave to his sister
= 75% x 128
= ⁷⁵₁₀₀ x 128
= 96 

(b)
Fraction of all the scones he gave away to his sister and his brother that were strawberry scones
= 1 - ⁵₇
= ²₇

2 u = 96

1 u = 96 ÷ 2 = 48

Number of apricot scones that Xavier gave to his sister and his brother
= 5 u
= 5 x 48
= 240

Number of apricot scones that Xavier gave to his sister
= 128 - 96
= 32

Number of apricot scones that Xavier gave to his brother
= 240 - 32
= 208

Answer(s): (a) 96; (b) 208
