PSLE At Paul's fruit stall,
34 of the kiwis were green and the rest were golden. He sold
12 of the total number of kiwis.
45 of the kiwis sold were green. 21 golden kiwis were left. How many green kiwis did Paul sell?

Green |
Golden |
Total |
Before |
3x5 = 15 u |
1x5 = 5 u |
4x5 = 20 u |
Change |
|
|
- 2x5 = - 10 u |
Comparing golden kiwis and green kiwis sold |
- 4x2 = - 8 u |
- 1x2 = - 2 u |
- 5x2 = - 10 u |
After |
7 u |
3 u |
2x5 = 10 u |
The total number of kiwis is the same. Make the denominators of the total number of kiwis the same.
12 =
24The number of kiwis sold is the repeated identity. Make the number of kiwis sold the same. LCM of 2 and 5 is 10.
3 u = 21
1 u = 21 ÷ 3 = 7
Number of green kiwis that Paul sold
= 8 u
= 8 x 7
= 56
Answer(s): 56
