- How many grapefruits did Archie have at first?

Before |
2x4 =
8 u |

- 1x4 =
- 4 u |
- 3 u |
After |
1x4 =
4 u |
4 u |
(a)
Fraction of the starfruits left
= 1 -
12 =
12 Fraction of the grapefruits left
= 1 -
37 =
47The number of starfruits and grapefruits left were the same. Make the number of starfruits and grapefruits left the same. LCM of 1 and 4 is 4.
Number of starfruits at first = 8 u
Number of grapefruits at first = 7 u
8 u = 112
1 u = 112 ÷ 8 = 14
Number of starfruits left
= 4 u
= 4 x 14
= 56
(b)
Number of grapefruits at first
= 7 u
= 7 x 14
= 98
Answer(s): (a) 56; (b) 98
