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
