Q How do you convert a percentage to a decimal?

Divide the percentage by 100 (or shift the decimal point two places to the left) and remove the '%' symbol. For example, 48.5% = 48.5 / 100 = 0.485.

Q How do you convert a decimal to a percentage?

Multiply the decimal number by 100 (or shift the decimal point two places to the right) and add the '%' symbol. For example, 0.0725 = 0.0725 × 100 = 7.25%.

Q How do you change mixed percentages like 12 1/2% into decimals?
