How do you convert 5 yards to inches using two unit multipliers?

Answer 1

This question can be simplified: If you only use one unit multiplier, then your

answer is simply 180 inches (36 inches in a yard, 5 yards). If you use two unit

multipliers, which takes more time, the process by which you get 180 inches is

as follows: 12 inches in a foot, times 3 feet in a yard (36 inches) times 5 yards

(180 inches).

===========================

But the question did specify the method of solution, which should remind us

that learning the method is more important than the answer to little problems

like this one.

A "unit multiplier" is a fraction with equal numerator and denominator, which is

therefore equal to ' 1 ', and you can multiply a measurement by it without changing

the value of the measurement.

Each of the fractions in the following procedure is equal to ' 1 ':

(5 yards) x ( 3 feet/yard ) x (12 inches/foot) = 180 inches
