(a)
Jen and Pamela used the same number of berries to bake cakes. Make the numerators the same. LCM of 3 and 2 is 6.
3x24x2 of Mary's berries =
2x35x3 of Pamela's berries
68 of Mary's berries =
615 of Pamela's berries
Total number of berries at first
= 8 u + 15 u
= 23 u
23 u = 46
1 u = 46 ÷ 23 = 2
Number of berries that each girl used
= 6 u
= 6 x 2
= 12
(b)
Total number of berries that both girls had left
= 2 u + 9 u
= 11 u
= 11 x 2
= 22
Answer(s): (a) 12; (b) 22
