Liam had dragonfruits and oranges. The ratio of dragonfruits to oranges was 8 : 3. After
45 of the dragonfruits and 98 oranges were sold, there were 8 times as many dragonfruits as oranges left. How many dragonfruits and oranges were sold?
| |
Dragonfruits |
Oranges |
Comparing dragonfruits
and oranges at first |
8x5 =
40 u |
3x5 =
15 u |
| Before |
5x8 =
40 u |
|
| Change |
- 4x8 =
- 32 u |
- 98 |
| After |
1x8 =
8 u |
|
Comparing dragonfruits
and oranges in the end |
8 u |
1 u |
The number of dragonfruits at first is repeated. Make the number of dragonfruits at first the same. LCM of 8 and 5 is 40.
Number of oranges sold
= 15 u - 1 u
= 14 u
14 u = 98
1 u = 98 ÷ 14 = 7
Number of dragonfruits and oranges sold
= 32 u + 98
= 32 x 7 + 98
= 224 + 98
= 322
Answer(s): 322
