At a shop, the ratio of papayas to coconuts was 7 : 12. After Elyse bought four-fifths of the coconuts, there was a total of 94 papayas and coconuts left at the shop. How many fruits were there at first?
|
Papayas |
Coconuts |
Total |
Comparing papayas and coconuts at first |
7x5 = 35 u |
12x5 = 60 u |
95 u |
Before |
|
5x12 = 60 u |
|
Change |
|
- 4x12 = - 48 u |
|
After |
35 u |
1x12 = 12 u |
94 |
The number of coconuts at first is repeated. Make the number of coconuts at first the same. LCM of 12 and 5 is 60.
Total number of fruits left
= 35 u + 12 u
= 47 u
47 u = 94
1 u = 94 ÷ 47 = 2
Number of fruits at first
= 35 u + 60 u
= 95 u
= 95 x 2
= 190
Answer(s): 190
