To solve the problem, we can break it into two parts:
**Part A:** To find the expression that represents the percent change in the family's home size, we use the formula for percent change, which is given by:
\[
\text{Percent Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}
\]
In this case:
- New Value = 2,400
- Old Value = 1,500
So the expression for Part A will be:
\[
\frac{2,400 - 1,500}{1,500}
\]
This corresponds to the option:
- **A: the fraction with numerator 2,400 minus 1,500 and denominator 1,500**
**Part B:** Next, we calculate the percent increase from the old home to the new home using the same formula. We can first calculate the difference and then compute the percent increase:
1. Calculate the difference in square footage:
\[
2,400 - 1,500 = 900
\]
2. Now calculate the percent increase:
\[
\text{Percent Increase} = \frac{900}{1,500} = 0.6
\]
To convert this to a percentage, multiply by 100:
\[
0.6 \times 100 = 60\%
\]
Thus, the answer for Part B is:
- **B: 60%** or **B: 60 percent**
**Final Answers:**
- Part A: **A: the fraction with numerator 2,400 minus 1,500 and denominator 1,500**
- Part B: **B: 60%** or **B: 60 percent**
**Part A:** To find the expression that represents the percent change in the family's home size, we use the formula for percent change, which is given by:

- Part B: **B: 60%** or **B: 60 percent**
