Answer 1

To find out how many 1/4-foot pieces are in a 5-foot roll of ribbon, you can divide the total length of the ribbon by the length of each piece:

\[
\text{Number of pieces} = \frac{\text{Total length of ribbon}}{\text{Length of each piece}} = \frac{5 \text{ feet}}{1/4 \text{ foot}}
\]

Dividing by a fraction is the same as multiplying by its reciprocal:

\[
\frac{5}{1/4} = 5 \times 4 = 20
\]

So, there are 20 pieces of 1/4-foot ribbon in a 5-foot roll.

The answer is \( \text{C. } 20 \).
