Gabriel had some cherry tarts and strawberry tarts. He gave away 88 tarts to his sister. 25% of them were cherry tarts and the rest were strawberry tarts.

1. How many strawberry tarts did he give his sister?
2. Gabriel gave some cherry tarts to his brother. ⁴₇ of all the tarts he gave away to his sister and his brother were cherry tarts. How many cherry tarts did he give his brother?

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

Number of strawberry tarts that Gabriel gave to his sister
= 75% x 88
= ⁷⁵₁₀₀ x 88
= 66 

(b)
Fraction of all the tarts he gave away to his sister and his brother that were strawberry tarts
= 1 - ⁴₇
= ³₇

3 u = 66

1 u = 66 ÷ 3 = 22

Number of cherry tarts that Gabriel gave to his sister and his brother
= 4 u
= 4 x 22
= 88

Number of cherry tarts that Gabriel gave to his sister
= 88 - 66
= 22

Number of cherry tarts that Gabriel gave to his brother
= 88 - 22
= 66

Answer(s): (a) 66; (b) 66
