4x2 =
8 u |

After |
1x2 =
2 u |
2 u |
(a)
Fraction of the mangoes left
= 1 -
34 =
14 Fraction of the pears left
= 1 -
57 =
27The number of mangoes and pears left were the same. Make the number of mangoes and pears left the same. LCM of 1 and 2 is 2.
Number of mangoes at first = 8 u
Number of pears at first = 7 u
8 u = 72
1 u = 72 ÷ 8 = 9
Number of mangoes left
= 2 u
= 2 x 9
= 18
(b)
Number of pears at first
= 7 u
= 7 x 9
= 63
Answer(s): (a) 18; (b) 63
