How to convert a decimal to a fraction

Write the number with decimal like this:


You must then multiply the decimal and the denominator (1) by 10 until you get a whole number at the level of the numerator. If you prefer to go faster, calculate the number of digits after the decimal point and add that same number of 0s after the 1 (or tens) in the denominator.

When there is no more decimal and therefore the figure becomes whole, you can simplify or reduce the resulting fraction.

Example conversion

0,0161 = 161000 = 2125
