(a)
Linda and Natalie used the same number of lychees to bake cakes. Make the numerators the same. LCM of 3 and 2 is 6.
3x28x2 of Mary's lychees =
2x35x3 of Natalie's lychees
616 of Mary's lychees =
615 of Natalie's lychees
Total number of lychees at first
= 16 u + 15 u
= 31 u
31 u = 248
1 u = 248 ÷ 31 = 8
Number of lychees that each girl used
= 6 u
= 6 x 8
= 48
(b)
Total number of lychees that both girls had left
= 10 u + 9 u
= 19 u
= 19 x 8
= 152
Answer(s): (a) 48; (b) 152
