## Converting a fraction to a decimal

To change a fraction to a decimal, you divide the top number by the bottom number (divide the numerator by the denominator).

## Converting a decimal into a fraction

When you change a terminating decimal to a fraction, the denominator will be 10, or 100, or 1000 or… (depending on the number of decimal places).

For example:

0.5 means 'five tenths', so 0.5 = ^{5}/_{10} = ^{1}/_{2}

0.45 means '45 hundredths', so 0.45 = ^{45}/_{100} = ^{9}/_{20}

0.240 means '240 thousandths', so 0.240 = ^{240}/_{1000} = ^{6}/_{25}
