What is the difference in strength between \(\frac13\)-hp and a \(\frac12\)-hp garage door opener?
Correct Answer
$\frac16$
Explanation
To calculate the difference, we subtract both the strengths
difference = \(\frac12 - \frac13\)
Let's find the least common denominator
$\text{LCD(2, 3) = 6}$
Now multiply both numerators and denominators as below
$\frac12 \cdot \frac33 - \frac13 \cdot \frac22 $
Now subtract the numerators
$= \frac36 - \frac26 = \frac16$
The difference is \(\frac16\)-hp
