Jade baked 85 biscuits. She ate
45 of them.
- How many biscuits had she eaten?
- How many biscuits had she left?
(a)
Total number of biscuits baked = 5 u
5 u = 85
1 u = 85 ÷ 5 = 17
Number of biscuits that Jade ate
= 4 u
= 4 x 17
= 68
(b)
Number of biscuits that Jade had left
= 85 - 68
= 17
Answer(s) : (a) 68; (b) 17
