Before |
3x2 =
6 u |

After |
2x2 =
4 u |
4 u |
(a)
Fraction of the pears left
= 1 -
13 =
23 Fraction of the dragonfruits left
= 1 -
37 =
47The number of pears and dragonfruits left were the same. Make the number of pears and dragonfruits left the same. LCM of 2 and 4 is 4.
Number of pears at first = 6 u
Number of dragonfruits at first = 7 u
6 u = 84
1 u = 84 ÷ 6 = 14
Number of pears left
= 4 u
= 4 x 14
= 56
(b)
Number of dragonfruits at first
= 7 u
= 7 x 14
= 98
Answer(s): (a) 56; (b) 98
