Nezavi [6.7K]

Answer: 3

Step-by-step explanation:

1. Convert the mixed number to fraction:

- Write the sum obtained as the numerator and rewrite the original denominator of the fraction.

Then:

$1\ 1/2=\frac{(1)(2)+1}{2}=\frac{3}{2}$

2. Multiply the numerators.

3. Multiply the denominator.

4. Reduce the fraction.

Then:

$(\frac{3}{2})(\frac{2}{1})=\frac{6}{2}=3$
