Abi baked 42 biscuits. She ate
23 of them.
- How many biscuits had she eaten?
- How many biscuits had she left?
(a)
Total number of biscuits baked = 3 u
3 u = 42
1 u = 42 ÷ 3 = 14
Number of biscuits that Abi ate
= 2 u
= 2 x 14
= 28
(b)
Number of biscuits that Abi had left
= 42 - 28
= 14
Answer(s) : (a) 28; (b) 14
