At a fruit stall, there were
13 as many oranges as persimmons. After 45 persimmons were sold, the number of oranges became
34 as many as the persimmons. How many fruits were at the fruit stall at first?
|
Oranges |
Persimmons |
Before |
1x3 = 3 u |
3x3 = 9 u |
Change |
|
- 45 |
After |
3x1 = 3 u |
4x1 = 4 u |
The number of oranges at first and in the end remains unchanged. Make the number of oranges the same. LCM of 1 and 3 is 3.
Number of persimmons sold
= 9 u - 4 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Number of fruits at first
= 3 u + 9 u
= 12 u
= 12 x 9
= 108
Answer(s): 108
