Penelope baked 300 puffs. She gave 40 puffs to Brandon and some puffs to Peter. She had
310 of the total puffs left.
- How many puffs did she have left?
- What fraction of the total puffs did she give to Peter?
(a)
Total number of puffs = 10 u
10 u = 300
1 u = 300 ÷ 10 = 30
Number of puffs that Penelope had left
= 3 u
= 3 x 30
= 90
(b)
Number of puffs that Tina gave to Peter
= 300 - 90 - 40
= 170
Fraction of the total puffs that Penelope gave to Peter
