Inessa05 [86]

Answer : The conversion used is, $1\text{ feet}=12\text{ inches}$

Explanation :

The conversion used :

$1\text{ feet}=12\text{ inches}$

For example : To convert 10 feet into inches.

$1\text{ feet}=12\text{ inches}$

$10\text{ feet}=10\text{ feet}\times \frac{12\text{ inches}}{1\text{ feet}}$

$=120\text{ inches}$

From this we conclude that, the conversion factor used in the numerator and denominator for 1 feet should be, $\frac{12\text{ inches}}{1\text{ feet}}$
