Nicole baked 209 cupcakes and macarons. She burnt 6 pieces and counted the remaining pieces.
15 of the macarons and
56 of the cupcakes were blueberry flavoured. There were equal number of macarons and cupcakes that were banana flavoured.
- How many unburnt banana cupcakes were there?
- What fraction of the unburnt pastries were blueberry cupcakes?
(a)
Number of pastries that was not burnt
= 209 - 6
= 203
Fraction of the macarons that was banana flavoured
= 1 -
15 =
45 Fraction of the cupcakes that was banana flavoured
= 1 -
56 =
16 The number of banana macarons and banana cupcakes was the same. Make the numerators the same.
45 Macarons =
1x46x4 Cupcakes
45 Macarons =
424 Cupcakes
Number of unburnt macarons = 5 u
Number of unburnt cupcakes = 24 u
Total number of unburnt pastries
= 5 u + 24 u
= 29 u
29 u = 203
1 u = 203 ÷ 29 = 7
Number of unburnt banana cupcakes
= 4 u
= 4 x 7
= 28
(b)
Number of unburnt blueberry cupcakes
= 24 u - 4 u
= 20 u
Unburnt blueberry cupcakesTotal unburnt pastries =
205 + 24 =
