To write the decimal number 0.7 as a percentage, follow these steps:

2. Take the decimal number you are given, which is 0.7.
3. To convert the decimal to a percentage, you multiply the decimal number by 100. This operation shifts the decimal point two places to the right.
4. Perform the multiplication:

0.7 \times 100 = 70
\][/tex]
5. Attach the percent symbol (%) to the result to indicate that it is a percentage.
Thus, when you convert 0.7 to a percentage, you obtain:
