3x2 =
6 u |

After |
1x2 =
2 u |
2 u |
(a)
Fraction of the oranges left
= 1 -
23 =
13 Fraction of the guavas left
= 1 -
35 =
25The number of oranges and guavas left were the same. Make the number of oranges and guavas left the same. LCM of 1 and 2 is 2.
Number of oranges at first = 6 u
Number of guavas at first = 5 u
6 u = 84
1 u = 84 ÷ 6 = 14
Number of oranges left
= 2 u
= 2 x 14
= 28
(b)
Number of guavas at first
= 5 u
= 5 x 14
= 70
Answer(s): (a) 28; (b) 70
