80 pupils travel to school. 10% on car, 3/20 on cycle, walk 25% and bus 1/2 what is the ratio of the numbers of pupils who travel by car to the numbers of pupils who take the bus

Answer 1

First, we need to calculate the number of pupils who travel by each mode of transport:

Car: 10% of 80 pupils = 0.10 x 80 = 8 pupils
Cycle: 3/20 of 80 pupils = (3/20) x 80 = 12 pupils
Walk: 25% of 80 pupils = 0.25 x 80 = 20 pupils
Bus: 1/2 of 80 pupils = (1/2) x 80 = 40 pupils

Now, we find the ratio of pupils who travel by car to those who take the bus:

8 pupils (car) : 40 pupils (bus)

Therefore, the ratio of the number of pupils who travel by car to the number of pupils who take the bus is 8:40, which can be simplified to 1:5.
