For every 30 biscuits that Adam bakes,
he bakes 10 wafers.
He bakes a total of 160 biscuits and wafers.
- How many wafers does he bake?
- How many more biscuits than wafers does he bake?
(a)
Number of biscuits and wafers per set
= 30 + 10
= 40
Number of sets
= 160 ÷ 40
= 4
Number of wafers that Adam bakes
= 4 x 10
= 40
(b) Number of biscuits that Adam bakes
= 4 x 30
= 120
Number of more biscuits than wafers
= 120 - 40
= 80
Answer(s): (a) 40; (b) 80
