Answer:
36 motorcycles
Explanation:
calculate
of 80
=
× 80 ( cancel 5 and 80 by 5 )
= 3 × 16 = 48
there are 48 motorcycles and buses
let x be the number of buses then 3x is the number of motorcycles , then
x + 3x = 48
4x = 48 ( divide both sides by 4 )
x = 12
number of motorcycles = 3x = 3 × 12 = 36
