There were some motorcycles, cars and vans.
58 of the total vehicles were motorcycles and cars. There were 81 vans and twice as many motorcycles as cars. How many more motorcycles than cars were there?
Motorcycles |
Cars |
Vans |
5x3 |
3x3 |
2x5 |
1x5 |
|
10 u |
5 u |
9 u |
The total number of motorcycles and cars is repeated. Make the total number of motorcycles and cars the same. LCM of 5 and 3 is 15.
Number of vans = 9 u
9 u = 81
1 u = 81 ÷ 9 = 9
Number of more motorcycles than cars
= 10 u - 5 u
= 5 u
= 5 x 9
= 45
Answer(s): 45
