How do we convert between decimal numbers and percentages?

To convert a decimal number to a percentage, we multiply the decimal number by 100.

Remember, when you multiply by 100, move all of the digits two places to the left.

0.75 x 100% = 75.0% = 75%

Look at the place value chart below to see the movement of the digits.

To convert a percentage to a decimal number, we divide the decimal number by 100.

Remember, when you divide by 100, move all of the digits two places to the right.

75% ÷ 100 = 0.75

Look at the place value chart below to see the movement of the digits.

Over to you now to have a go at some practice questions...good luck!
