Question

What is the rate and the unit rate of 30 chairs in 3 rows?

Answer 1

To find the rate and the unit rate of 30 chairs in 3 rows, we can start by calculating the rate of chairs per row and then determine the unit rate.

1. **Rate of chairs per row:**
- Since there are 30 chairs and 3 rows:
\[
\text{Rate} = \frac{\text{Total Chairs}}{\text{Number of Rows}} = \frac{30 \text{ chairs}}{3 \text{ rows}} = 10 \text{ chairs per row}
\]

2. **Unit Rate:**
- The unit rate typically refers to the amount of one item per 1 unit of another. In this case, the unit rate can be considered as the number of chairs per 1 row.
- Thus, the unit rate is:
\[
\text{Unit Rate} = 10 \text{ chairs per row}
\]

In summary:
- The rate is 10 chairs per row.
- The unit rate is also 10 chairs per row.
