Peter had some vanilla puffs and banana puffs. He gave away 176 puffs to his brother. 25% of them were vanilla puffs and the rest were banana puffs.
- How many banana puffs did he give his brother?
- Peter gave some vanilla puffs to his sister. 35 of all the puffs he gave away to his brother and his sister were vanilla puffs. How many vanilla puffs did he give his sister?
(a)
Percentage of banana puffs
= 100% - 25%
= 75%
Number of banana puffs that Peter gave to his brother
= 75% x 176
=
75100 x 176
= 132
(b)
Fraction of all the puffs he gave away to his brother and his sister that were banana puffs
= 1 -
35=
252 u = 132
1 u = 132 ÷ 2 = 66
Number of vanilla puffs that Peter gave to his brother and his sister
= 3 u
= 3 x 66
= 198
Number of vanilla puffs that Peter gave to his brother
= 176 - 132
= 44
Number of vanilla puffs that Peter gave to his sister
= 198 - 44
= 154
Answer(s): (a) 132; (b) 154
