Risa baked 48 shortbreads. She ate
23 of them.
- How many shortbreads had she eaten?
- How many shortbreads had she left?
(a)
Total number of shortbreads baked = 3 u
3 u = 48
1 u = 48 ÷ 3 = 16
Number of shortbreads that Risa ate
= 2 u
= 2 x 16
= 32
(b)
Number of shortbreads that Risa had left
= 48 - 32
= 16
Answer(s) : (a) 32; (b) 16
