12 of the starfruits and

- How many starfruits were left?
- How many guavas did Billy have at first?

Before |
2x4 =
8 u |
7 u |

- 1x4 =
- 4 u |
- 3 u |
After |
1x4 =
4 u |
4 u |
(a)
Fraction of the starfruits left
= 1 -
12 =
12 Fraction of the guavas left
= 1 -
37 =
47The number of starfruits and guavas left were the same. Make the number of starfruits and guavas left the same. LCM of 1 and 4 is 4.
Number of starfruits at first = 8 u
Number of guavas at first = 7 u
8 u = 72
1 u = 72 ÷ 8 = 9
Number of starfruits left
= 4 u
= 4 x 9
= 36
(b)
Number of guavas at first
= 7 u
= 7 x 9
= 63
Answer(s): (a) 36; (b) 63
