houses

Explanation:

Step1: Convert percentage to decimal

To find 70% of 10,000, we first convert 70% to a decimal. 70% is equivalent to $0.7$ (since $70\%=\frac{70}{100} = 0.7$).

Step2: Multiply the total number of houses by the decimal

We multiply the total number of houses (10,000) by the decimal we found in Step 1. So the calculation is $10000\times0.7$.
Calculating $10000\times0.7 = 7000$.

Answer:

7000
