Question

When converting from inches to feet , the measurement in inches,m, of an object varies directly with its measurement in feet, f, with the constant of variation being 12. What is the equation relating these two quantities?

Answer 1

m = 12f

Or

m/12 = f

Explanation:

The conversion from inches to feet involves a constant factor of variation which is 12. Inches is a smaller unit while feet are obtained by dividing the inches with 12.

As we know,

1 foot = 12 inches

Given in the question:

m = measurement in inches

and

f= measurement in feet

Hence the equation will be:

m = 12f

Or

m/12 = f ..
