Answer 1

To determine how many bookcases Victoria can paint, we need to use the amount of paint she has and the amount of paint required for each bookcase.

1. **Total paint available**: 2 gallons
2. **Paint required per bookcase**: \( \frac{1}{8} \) gallon

Next, we can calculate the total number of bookcases that can be painted by dividing the total amount of paint by the amount of paint needed for one bookcase.

\[
\text{Number of bookcases} = \frac{\text{Total paint}}{\text{Paint per bookcase}} = \frac{2 \text{ gallons}}{\frac{1}{8} \text{ gallon per bookcase}}
\]

To divide by a fraction, we multiply by its reciprocal:

\[
\text{Number of bookcases} = 2 \times 8 = 16
\]

So, Victoria will be able to paint **16 bookcases**.

To summarize:
- We approached the problem using division, knowing the total paint and the size of the groups (each bookcase).
- The unknown we solved for was the number of bookcases she can paint.
