You could just plug it into a calculator, 19 divided by 40 will give your answer.
To do it on paper:
Turn the fraction into a percentage...
19 / 40 = x / 100 Cross multiply...
1900 = 40x Solve for x
x = 47.5 %
Since this is a percentage and we want a decimal, just divide by 100, or simply move the decimal 2 places to the left.
The decimal form is .475

you divide 19 by 40. When changing a fraction into a decimal you always divide the top number by the bottom number.

Either divide, or build up so the denominator is a power of ten.
19/40*(25/25)
475/1000 = 0.475
