PSLE At Ivan's fruit stall,
56 of the apples were green and the rest were red. He sold
13 of the total number of apples.
45 of the apples sold were green. 24 red apples were left. How many green apples did Ivan sell?
|
Green |
Red |
Total |
Before |
5x5 = 25 u |
1x5 = 5 u |
6x5 = 30 u |
Change |
|
|
- 2x5 = - 10 u |
Comparing red apples and green apples sold |
- 4x2 = - 8 u |
- 1x2 = - 2 u |
- 5x2 = - 10 u |
After |
17 u |
3 u |
4x5 = 20 u |
The total number of apples is the same. Make the denominators of the total number of apples the same.
13 =
26The number of apples sold is the repeated identity. Make the number of apples sold the same. LCM of 2 and 5 is 10.
3 u = 24
1 u = 24 ÷ 3 = 8
Number of green apples that Ivan sold
= 8 u
= 8 x 8
= 64
Answer(s): 64
