(a)
Fanny and Raeann used the same number of lychees to bake cakes. Make the numerators the same. LCM of 3 and 2 is 6.
3x24x2 of Mary's lychees =
2x37x3 of Raeann's lychees
68 of Mary's lychees =
621 of Raeann's lychees
Total number of lychees at first
= 8 u + 21 u
= 29 u
29 u = 203
1 u = 203 ÷ 29 = 7
Number of lychees that each girl used
= 6 u
= 6 x 7
= 42
(b)
Total number of lychees that both girls had left
= 2 u + 15 u
= 17 u
= 17 x 7
= 119
Answer(s): (a) 42; (b) 119
