Esther baked 99 cupcakes. She ate
711 of them.
- How many cupcakes had she eaten?
- How many cupcakes had she left?
(a)
Total number of cupcakes baked = 11 u
11 u = 99
1 u = 99 ÷ 11 = 9
Number of cupcakes that Esther ate
= 7 u
= 7 x 9
= 63
(b)
Number of cupcakes that Esther had left
= 99 - 63
= 36
Answer(s) : (a) 63; (b) 36
