Answer:

30

Step-by-step explanation:

[tex]\frac{75}{100} = \frac{x}{40}\\\\Cross- multiply:\\\\\\75*40=100x[/tex]

3000 = 100x

x = 30

Another way:

75/100 is in reality 3/4

and 3/4 of 40 = 30

40/4 = 10

10 * 3 = 30

The answer is 30

Because its looking for 75% of 40, you have to turn 75% into a decimal by moving the placement by two.
75 turn into .75
After you do that you multiply 40 by .75 and you get 30, which is your answer. :)
