Olivia baked 55 puffs. She ate
711 of them.
- How many puffs had she eaten?
- How many puffs had she left?
(a)
Total number of puffs baked = 11 u
11 u = 55
1 u = 55 ÷ 11 = 5
Number of puffs that Olivia ate
= 7 u
= 7 x 5
= 35
(b)
Number of puffs that Olivia had left
= 55 - 35
= 20
Answer(s) : (a) 35; (b) 20
