- How many mangosteens did Gabriel have at first?

Before |
3x4 =
12 u |
7 u |

- 2x4 =
- 4 u |
- 3 u |
After |
1x4 =
4 u |
4 u |
(a)
Fraction of the pears left
= 1 -
23 =
13 Fraction of the mangosteens left
= 1 -
37 =
47The number of pears and mangosteens left were the same. Make the number of pears and mangosteens left the same. LCM of 1 and 4 is 4.
Number of pears at first = 12 u
Number of mangosteens at first = 7 u
12 u = 96
1 u = 96 ÷ 12 = 8
Number of pears left
= 4 u
= 4 x 8
= 32
(b)
Number of mangosteens at first
= 7 u
= 7 x 8
= 56
Answer(s): (a) 32; (b) 56
