Rachel baked 72 shortbreads. She ate
34 of them.
- How many shortbreads had she eaten?
- How many shortbreads had she left?
(a)
Total number of shortbreads baked = 4 u
4 u = 72
1 u = 72 ÷ 4 = 18
Number of shortbreads that Rachel ate
= 3 u
= 3 x 18
= 54
(b)
Number of shortbreads that Rachel had left
= 72 - 54
= 18
Answer(s) : (a) 54; (b) 18
