Hi, I've been stuck on this stupid math test all day long, the question is "if 1/4 inch represents 50 miles, how many inches represent 225 miles?" I did the math and know the answer is 1 1/8 but I just don't know how to show my work. Can anyone help me?

Answer 1

use a simple ratio ...

.25 inches/50 miles = x inches/225 miles
.25/50 = x/225 , after multiplying both sides (by miles/inches)
50x = .25(225)
x = 56.25/50 = 1.128 or 1 1/8 <---- your answer

or
225/50 = 4.5 = 9/2
so we have to multiply 1/4 by 9/2
(1/4)(9/2) = 9/8 = 1 1/8
