Answer:

#196/5#

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

Explanation:

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#
