Draw 4 squares. The perimeter is 10 because the width is 4 and the length is 1. So 4 x 2 is 8 and 1 x 2 is 2. And 8 + 2 = 10.
6,000,000+ 300,000+ 60000+ 2000+ 40+ 9
Given the ratio of cars, trucks and motorcycles 7:5:2 and the total number of cars is 48, to get the number of motorcycles we proceed as follows:
fraction of cars to total number
(5+7)/(7+5+2)
=12/14
=6/7
the total number of cars, trucks and motorcycles will be:
1/(6/7)×48
=56
total number motorcycles
2/14*56
=8 motorcycles
