Answer:

  x/50 = 40/100

  x = 20

Step-by-step explanation:

It is useful to remember that the symbol % is a shorthand way to write /100. (Similarly, the symbol ‰ is a shorthand way to write /1000.) This means the number 40% represents the ratio 40/100. In decimal, that is 0.40 (forty hundredths).

When this is the fraction that represents the number of test questions that are correct, you can see that the proportion should be ...

  correct / total questions = x / 50 = 40 / 100 . . . . the desired proportion

Multiplying by 50 gives the value of x:

  x = 50(0.40)

  x = 20 . . . . the value of x
