Asher had some cheese cupcakes and apple cupcakes. He gave away 75 cupcakes to his cousin. 20% of them were cheese cupcakes and the rest were apple cupcakes.
- How many apple cupcakes did he give his cousin?
- Asher gave some cheese cupcakes to his sister. 37 of all the cupcakes he gave away to his cousin and his sister were cheese cupcakes. How many cheese cupcakes did he give his sister?
(a)
Percentage of apple cupcakes
= 100% - 20%
= 80%
Number of apple cupcakes that Asher gave to his cousin
= 80% x 75
=
80100 x 75
= 60
(b)
Fraction of all the cupcakes he gave away to his cousin and his sister that were apple cupcakes
= 1 -
37=
474 u = 60
1 u = 60 ÷ 4 = 15
Number of cheese cupcakes that Asher gave to his cousin and his sister
= 3 u
= 3 x 15
= 45
Number of cheese cupcakes that Asher gave to his cousin
= 75 - 60
= 15
Number of cheese cupcakes that Asher gave to his sister
= 45 - 15
= 30
Answer(s): (a) 60; (b) 30
