Question

There are 16 cars and 64 passengers scheduled to go to a concert write a ratio in simplest form that compares the number of passengers to the number of cars

Answer 1

1:4.  16 is 25% of 64, or 1/4, this translates to 1:4 in ratio form.

Answer 2

The ratio would be 16:64

divide both sides by 16, and you will get 1:4 (that's number of cars to passengers)

if you want to compare passengers to cars (not sure if you mistyped it), it's 4:1
