Liam had some chocolate chip muffins and strawberry muffins. He gave away 196 muffins to his sister. 25% of them were chocolate chip muffins and the rest were strawberry muffins.

1. How many strawberry muffins did he give his sister?
2. Liam gave some chocolate chip muffins to his cousin. ²₅ of all the muffins he gave away to his sister and his cousin were chocolate chip muffins. How many chocolate chip muffins did he give his cousin?

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

Number of strawberry muffins that Liam gave to his sister
= 75% x 196
= ⁷⁵₁₀₀ x 196
= 147 

(b)
Fraction of all the muffins he gave away to his sister and his cousin that were strawberry muffins
= 1 - ²₅
= ³₅

3 u = 147

1 u = 147 ÷ 3 = 49

Number of chocolate chip muffins that Liam gave to his sister and his cousin
= 2 u
= 2 x 49
= 98

Number of chocolate chip muffins that Liam gave to his sister
= 196 - 147
= 49

Number of chocolate chip muffins that Liam gave to his cousin
= 98 - 49
= 49

Answer(s): (a) 147; (b) 49
