For every 40 biscuits that Adam bakes,
he bakes 30 shortbreads.
He bakes a total of 140 biscuits and shortbreads.
- How many shortbreads does he bake?
- How many more biscuits than shortbreads does he bake?
(a)
Number of biscuits and shortbreads per set
= 40 + 30
= 70
Number of sets
= 140 ÷ 70
= 2
Number of shortbreads that Adam bakes
= 2 x 30
= 60
(b) Number of biscuits that Adam bakes
= 2 x 40
= 80
Number of more biscuits than shortbreads
= 80 - 60
= 20
Answer(s): (a) 60; (b) 20
