Comparing papayas
and oranges at first |
5x1 =
5 u |
12x1 =
12 u |
17 u |
Before |
|
3x4 =
12 u |
|
Change |
|
- 2x4 =
- 8 u |
|
After |
5 u |
1x4 =
4 u |
63 |
The number of oranges at first is repeated. Make the number of oranges at first the same. LCM of 12 and 3 is 12.
Total number of fruits left
= 5 u + 4 u
= 9 u
9 u = 63
1 u = 63 ÷ 9 = 7
Number of fruits at first
= 5 u + 12 u
= 17 u
= 17 x 7
= 119
Answer(s): 119
