For every 90 shortbreads that Adam bakes,
he bakes 70 puffs.
He bakes a total of 160 shortbreads and puffs.
- How many puffs does he bake?
- How many more shortbreads than puffs does he bake?
(a)
Number of shortbreads and puffs per set
= 90 + 70
= 160
Number of sets
= 160 ÷ 160
= 1
Number of puffs that Adam bakes
= 1 x 70
= 70
(b) Number of shortbreads that Adam bakes
= 1 x 90
= 90
Number of more shortbreads than puffs
= 90 - 70
= 20
Answer(s): (a) 70; (b) 20
