PSLE At Vaidev's fruit stall,
79 of the apples were red and the rest were green. He sold
13 of the total number of apples.
35 of the apples sold were red. 24 green apples were left. How many green apples did Vaidev sell?
|
Red |
Green |
Total |
Before |
7x5 = 35 u |
2x5 = 10 u |
9x5 = 45 u |
Change |
|
|
- 3x5 = - 15 u |
Comparing green apples and red apples sold |
- 3x3 = - 9 u |
- 2x3 = - 6 u |
- 5x3 = - 15 u |
After |
26 u |
4 u |
6x5 = 30 u |
The total number of apples is the same. Make the denominators of the total number of apples the same.
13 =
39The number of apples sold is the repeated identity. Make the number of apples sold the same. LCM of 3 and 5 is 15.
4 u = 24
1 u = 24 ÷ 4 = 6
Number of green apples that Vaidev sold
= 6 u
= 6 x 6
= 36
Answer(s): 36
