Olivia baked 466 muffins and puffs. She burnt 6 pieces and counted the remaining pieces.
16 of the puffs and
78 of the muffins were vanilla flavoured. There were equal number of puffs and muffins that were banana flavoured.
- How many unburnt banana muffins were there?
- What fraction of the unburnt pastries were vanilla muffins?
(a)
Number of pastries that was not burnt
= 466 - 6
= 460
Fraction of the puffs that was banana flavoured
= 1 -
16 =
56 Fraction of the muffins that was banana flavoured
= 1 -
78 =
18 The number of banana puffs and banana muffins was the same. Make the numerators the same.
56 Puffs =
1x58x5 Muffins
56 Puffs =
540 Muffins
Number of unburnt puffs = 6 u
Number of unburnt muffins = 40 u
Total number of unburnt pastries
= 6 u + 40 u
= 46 u
46 u = 460
1 u = 460 ÷ 46 = 10
Number of unburnt banana muffins
= 5 u
= 5 x 10
= 50
(b)
Number of unburnt vanilla muffins
= 40 u - 5 u
= 35 u
Unburnt vanilla muffinsTotal unburnt pastries =
356 + 40 =
3546 Answer(s): (a) 50; (b)
3546
