PSLE At Cody's fruit stall,
89 of the kiwis were golden and the rest were green. He sold
13 of the total number of kiwis.
45 of the kiwis sold were golden. 26 green kiwis were left. How many green kiwis did Cody sell?

Golden |
Green |
Total |
Before |
8x5 = 40 u |
1x5 = 5 u |
9x5 = 45 u |
Change |
|
|
- 3x5 = - 15 u |
Comparing green kiwis and golden kiwis sold |
- 4x3 = - 12 u |
- 1x3 = - 3 u |
- 5x3 = - 15 u |
After |
28 u |
2 u |
6x5 = 30 u |
The total number of kiwis is the same. Make the denominators of the total number of kiwis the same.
13 =
39The number of kiwis sold is the repeated identity. Make the number of kiwis sold the same. LCM of 3 and 5 is 15.
2 u = 26
1 u = 26 ÷ 2 = 13
Number of green kiwis that Cody sold
= 3 u
= 3 x 13
= 39
Answer(s): 39
