Answer:

80

Explanation:

There are two ways to do this:
#4/0.05#

1) we can think of the #0.05# as a fraction #5/100#. If we then write the fraction as #4/(5/100)# we can use a property of fractions when they are in the denominator, which is, we flip them upside down and multiply by the numerator, making it look like this: #4*100/5=4*20=80#

2) we can multiply the top and bottom of that by 100 leaving us with #400/5=80#
