Daniel had some cheese puffs and cherry puffs. He gave away 152 puffs to his sister. 25% of them were cheese puffs and the rest were cherry puffs.
- How many cherry puffs did he give his sister?
- Daniel gave some cheese puffs to his brother. 47 of all the puffs he gave away to his sister and his brother were cheese puffs. How many cheese puffs did he give his brother?
(a)
Percentage of cherry puffs
= 100% - 25%
= 75%
Number of cherry puffs that Daniel gave to his sister
= 75% x 152
=
75100 x 152
= 114
(b)
Fraction of all the puffs he gave away to his sister and his brother that were cherry puffs
= 1 -
47=
373 u = 114
1 u = 114 ÷ 3 = 38
Number of cheese puffs that Daniel gave to his sister and his brother
= 4 u
= 4 x 38
= 152
Number of cheese puffs that Daniel gave to his sister
= 152 - 114
= 38
Number of cheese puffs that Daniel gave to his brother
= 152 - 38
= 114
Answer(s): (a) 114; (b) 114
