The answer is x equals 24
you set up a proportion new over old

so x over 3
we then make them equal to each other
40 x
—- = —-
5 3
cross multiply, then we get
120=5x
isolate the x by dividing 5 from both sides to get 24
There is nothing in the space. If there were, then the space would not be blank.
