Jaslyn baked 72 cookies. She ate
23 of them.
- How many cookies had she eaten?
- How many cookies had she left?
(a)
Total number of cookies baked = 3 u
3 u = 72
1 u = 72 ÷ 3 = 24
Number of cookies that Jaslyn ate
= 2 u
= 2 x 24
= 48
(b)
Number of cookies that Jaslyn had left
= 72 - 48
= 24
Answer(s) : (a) 48; (b) 24
