Barbara baked 87 cupcakes. She ate
23 of them.
- How many cupcakes had she eaten?
- How many cupcakes had she left?
(a)
Total number of cupcakes baked = 3 u
3 u = 87
1 u = 87 ÷ 3 = 29
Number of cupcakes that Barbara ate
= 2 u
= 2 x 29
= 58
(b)
Number of cupcakes that Barbara had left
= 87 - 58
= 29
Answer(s) : (a) 58; (b) 29
