37 of the total puffs left.
- How many puffs did she have left?
- What fraction of the total puffs did she give to Vaidev?
(a)
Total number of puffs = 7 u
7 u = 280
1 u = 280 ÷ 7 = 40
Number of puffs that Xylia had left
= 3 u

= 120
(b)
Number of puffs that Tina gave to Vaidev
= 280 - 120 - 70
= 90
Fraction of the total puffs that Xylia gave to Vaidev
