Shiyun baked 50 shortbreads. She ate
35 of them.
- How many shortbreads had she eaten?
- How many shortbreads had she left?
(a)
Total number of shortbreads baked = 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Number of shortbreads that Shiyun ate
= 3 u
= 3 x 10
= 30
(b)
Number of shortbreads that Shiyun had left
= 50 - 30
= 20
Answer(s) : (a) 30; (b) 20
