At a fruit stall, there were 936 apples and oranges at first.
14 of the apples and
18 of the oranges were sold. In the end, there were same number of apples and oranges. How many less oranges than apples were sold?
| |
Apples |
Oranges |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing apples
and oranges in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of apples and oranges in the end is the same. Make the number of apples and oranges in the end the same. LCM of 3, 7 and 1 is 21.
Number of apples and oranges in the end
= 28 u + 24 u
= 52 u
52 u = 936
1 u = 936 ÷ 52 = 18
Number of less oranges than apples were sold
= 7 u - 3 u
= 4 u
= 4 x 18
= 72
Answer(s): 72
