For every 50 wafers that Adam bakes,
he bakes 20 puffs.
He bakes a total of 140 wafers and puffs.
- How many puffs does he bake?
- How many more wafers than puffs does he bake?
(a)
Number of wafers and puffs per set
= 50 + 20
= 70
Number of sets
= 140 ÷ 70
= 2
Number of puffs that Adam bakes
= 2 x 20
= 40
(b) Number of wafers that Adam bakes
= 2 x 50
= 100
Number of more wafers than puffs
= 100 - 40
= 60
Answer(s): (a) 40; (b) 60
