To find out how many dresses Reggie can make with 3 yards of fabric, you need to divide the total amount of fabric by the amount needed for each dress.
He has 3 yards of fabric, and each dress uses \(\frac{3}{8}\) yards.
Here's the calculation:
\[ \text{Number of dresses} = \frac{3 \text{ yards}}{\frac{3}{8} \text{ yards/dress}} \]
When dividing by a fraction, you multiply by the reciprocal:
\[ = 3 \times \frac{8}{3} \]
Now, calculate it:
\[ = \frac{3 \times 8}{3} = 8 \]
So, Reggie can make 8 dresses.
