80 pupils travel to school. 10% on car, 3/20 on cycle, walk 25% and bus 1/2 how many pupils cycle to school show working

Answer 1

To find out how many pupils cycle to school, we need to calculate the number of pupils in each mode of transportation first.

10% of 80 pupils travel by car:
10% of 80 = 0.10 x 80 = 8 pupils

3/20 of 80 pupils travel by cycle:
3/20 of 80 = (3/20) x 80 = 12 pupils

25% of 80 pupils walk:
25% of 80 = 0.25 x 80 = 20 pupils

1/2 of 80 pupils travel by bus:
1/2 of 80 = (1/2) x 80 = 40 pupils

Therefore, 12 pupils cycle to school.
