95

Explanation:

A percentage is found by taking the smaller number divided by the larger number times 100. Using this concept when can set up our equation.

#(38)/(x)*100=40%#

Now we can solve for x. First, we do this by dividing 100 to both sides of the equation, giving us:

#38/x=0.4#

The next step is to rearrange our equation to get x by itself. To do this we have to time x to both sides of the equation, giving us:

#38=0.4x#

We can now divide both side by 0.4 to give us our final answer:

#x=38/0.4=95#
