Answer:
When you rewrite a percent as a decimal, you need to move the decimal point two places to the left because a percent is a ratio that compares a number to 100. For example, 50% is the same as 50/100 or 0.5. To convert 50% to a decimal, you need to divide 50 by 100, which gives you 0.5. Moving the decimal point two places to the left achieves the same result.
Similarly, when you rewrite a decimal as a percent, you need to move the decimal point two places to the right because a percent expresses a number as a fraction of 100. For example, 0.75 is the same as 75/100 or 75%. To convert 0.75 to a percent, you need to multiply it by 100, which gives you 75. Moving the decimal point two places to the right achieves the same result.
