There were some cars, vans and buses.
25 of the total vehicles were cars and vans. There were 36 buses and thrice as many cars as vans. How many more cars than vans were there?
Cars |
Vans |
Buses |
2x2 |
3x2 |
3x1 |
1x1 |
|
3 u |
1 u |
6 u |
The total number of cars and vans is repeated. Make the total number of cars and vans the same. LCM of 2 and 4 is 4.
Number of buses = 6 u
6 u = 36
1 u = 36 ÷ 6 = 6
Number of more cars than vans
= 3 u - 1 u
= 2 u
= 2 x 6
= 12
Answer(s): 12
