- How many persimmons did Michael have at first?

5x2 =
10 u |

2 u |
(a)
Fraction of the starfruits left
= 1 -
25 =
35 Fraction of the persimmons left
= 1 -
57 =
27The number of starfruits and persimmons left were the same. Make the number of starfruits and persimmons left the same. LCM of 3 and 2 is 6.
Number of starfruits at first = 10 u
Number of persimmons at first = 7 u
10 u = 50
1 u = 50 ÷ 10 = 5
Number of starfruits left
= 2 u
= 2 x 5
= 10
(b)
Number of persimmons at first
= 7 u
= 7 x 5
= 35
Answer(s): (a) 10; (b) 35
