(a)
Kylie and Cindy used the same number of raspberries to bake cakes. Make the numerators the same. LCM of 5 and 4 is 20.
5x48x4 of Mary's raspberries =
4x57x5 of Cindy's raspberries
2032 of Mary's raspberries =
2035 of Cindy's raspberries
Total number of raspberries at first
= 32 u + 35 u
= 67 u
67 u = 268
1 u = 268 ÷ 67 = 4
Number of raspberries that each girl used
= 20 u
= 20 x 4
= 80
(b)
Total number of raspberries that both girls had left
= 12 u + 15 u
= 27 u
= 27 x 4
= 108
Answer(s): (a) 80; (b) 108
