$196/5$

(or $39 1/5$ or $39.2$ )

First, we need to turn $40$ into a fraction with $5$ as the denominator. We can do this by multiplying $5$ to both the numerator and the denominator.

$40/1 times 5/5 = (40times5)/(1times5) = 200/5$

Now that we have two fractions with common denominators, we can go ahead and subtract.

$200/5 - 4/5 = (200-4)/5 = 196/5$

Mixed fraction form:

$196/5 = 39 1/5$

Decimal form:

$196/5=39.2$
