Question

Enter the missing value into the box to complete the ratio comparing 75 centimeters to 3 meters. 1 :__

Answer 1

The ratio is written as a:b = c:d, by proportion using the same given, it is written as a/b = c/d. In the problem, d is the missing number, so we will cross multiply it to get the value, 

d = cb / a
d = (3)(1) / 75
d = 3/75 = 1/25
