(a)
Linda and Victoria used the same number of berries to bake cakes. Make the numerators the same. LCM of 2 and 5 is 10.
2x57x5 of Mary's berries =
5x28x2 of Victoria's berries
1035 of Mary's berries =
1016 of Victoria's berries
Total number of berries at first
= 35 u + 16 u
= 51 u
51 u = 204
1 u = 204 ÷ 51 = 4
Number of berries that each girl used
= 10 u
= 10 x 4
= 40
(b)
Total number of berries that both girls had left
= 25 u + 6 u
= 31 u
= 31 x 4
= 124
Answer(s): (a) 40; (b) 124
