Fraction of apple cupcakes left
= 1 -
57 =
27Fraction of pandan cupcakes left
= 1 -
14 =
34The number of apple cupcakes and pandan cupcakes in the end is the same. Make the numerators the same. LCM of 3 and 2 is 6.
27 of apple cupcakes =
34 of pandan cupcakes
621 of apple cupcakes =
68 of pandan cupcakes
Number of more apple cupcakes than pandan cupcakes at first
= 21 u - 8 u
= 13 u
13 u = 52
1 u = 52 ÷ 13 = 4
Number of apple cupcakes that Raeann gave away
= 21 u - 6 u
= 15 u
= 15 x 4
= 60
Answer(s): 60
