Explanation:

First Question (Write the decimal as a percent: 0.8)

Step1: Recall decimal to percent conversion

To convert a decimal to a percent, multiply the decimal by 100 (or move the decimal point two places to the right).
For \( 0.8 \), multiply by 100: \( 0.8\times100 = 80 \), so \( 0.8 = 80\% \).

Step1: Convert percent to decimal

To find a percentage of a number, first convert the percent to a decimal by dividing by 100. So, \( 12.8\% = \frac{12.8}{100}=0.128 \).

Step2: Multiply by the number

Now, find \( 0.128\times625 \). Calculate \( 0.128\times625 = 80 \).

Answer:

A. 80%
