## How to convert a decimal into a fraction ...

The most simple and facile way to convert a decimal to a fraction is by considering that the denominator will be 10, or 100, or 1000 or… (depending on the number of decimal places in the value you transform).

For instance:

0.4 represents 'four tenths', and so 0.4 = ^{4}/_{10} = ^{2}/_{5}

0.35 is '35 hundredths', and so 0.35 = ^{35}/_{100} = ^{7}/_{20}

0.550 means '550 thousandths', and so 0.550 = ^{550}/_{1000} = ^{11}/_{20}
