PSLE At Owen's fruit stall,
14 of the apples were green and the rest were red. He sold
12 of the total number of apples.
25 of the apples sold were green. 117 red apples were left. How many green apples did Owen sell?

Total |
Before |
1x5 = 5 u |
3x5 = 15 u |
4x5 = 20 u |
Change |
|
|
- 2x5 = - 10 u |
Comparing red apples and green apples sold |
- 2x2 = - 4 u |
- 3x2 = - 6 u |
- 5x2 = - 10 u |
After |
1 u |
9 u |
2x5 = 10 u |
The total number of apples is the same. Make the denominators of the total number of apples the same.
12 =
24The number of apples sold is the repeated identity. Make the number of apples sold the same. LCM of 2 and 5 is 10.
9 u = 117
1 u = 117 ÷ 9 = 13
Number of green apples that Owen sold
= 4 u
= 4 x 13
= 52
Answer(s): 52
