In converting a decimal into a fraction, you can use this formula that I generate:

$\text{ Fraction = }\frac{Decimal\text{ x 100}}{100}$

Then you simplify the fraction by dividing with the GCF of the numerator and denominator.

Let's convert 0.40 into a fraction,

$\text{ Fraction = }\frac{0.40\text{ x 100}}{100}\text{ = }(40)/(100)$

The GCF of 40 and 100 is 20. Let's simplify the fraction.

$\text{Numberator = }(40)/(20)\text{ = 2 ; Denominator = }(100)/(20)\text{ = 5}$
$\text{ 0.40 in fractional form is }(2)/(5)$

Therefore, the fractional form of 0.40 is 2/5.
