PSLE At Rael's fruit stall,
89 of the kiwis were green and the rest were golden. He sold
13 of the total number of kiwis.
45 of the kiwis sold were green. 14 golden kiwis were left. How many golden kiwis did Rael sell?

Green |
Golden |
Total |
Before |
8x5 = 40 u |
1x5 = 5 u |
9x5 = 45 u |
Change |
|
|
- 3x5 = - 15 u |
Comparing golden kiwis and green 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 = 14
1 u = 14 ÷ 2 = 7
Number of golden kiwis that Rael sold
= 3 u
= 3 x 7
= 21
Answer(s): 21
