To multiply \( \frac{5}{12} \) by \( 2 \), you can write \( 2 \) as a fraction:
\[ \frac{5}{12} \times \frac{2}{1} = \frac{5 \times 2}{12 \times 1} = \frac{10}{12} \]
Now, simplify \( \frac{10}{12} \) by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is \( 2 \):
\[ \frac{10 \div 2}{12 \div 2} = \frac{5}{6} \]
Thus, the answer in simplest form is \( \frac{5}{6} \).
