Answer
$\displaystyle \frac{60}{43}$
Work Step by Step
Reducing a Fraction to Its Lowest Terms
1. Write the prime factorizations of the numerator and the denominator.
2. Divide the numerator and the denominator by the greatest common factor, the product of all factors common to both. ---
$\begin{array}{llll}
120 & =2\times 60, & 86 & =2\times 43\\
& =2\times 2\times 15 & & \\
& =2\times 2\times 3\times 5 & & \\
& & & \\
GCF & =2 & & \\
& & &
\end{array}$
$\displaystyle \frac{120}{86}=\frac{120\div 2}{86\div 2}=\frac{60}{43}$
