Question

dentify the percent, amount, and base in this problem. 75% of what number is 30?

Answer 1

Answer:

40

Step-by-step explanation:

This is essentially just (4/3), or $\frac{3}{4}^{-1}$. (4/3)*30 = 40, so our answer must be 40. Just to check, taking 75 percent of 40, we indeed get 30!

Answer 2

For this case we must find a number of which 30 represents 75%. For this, we make a rule of three:

x ------------> 100%

30 ----------> 75%

Where the variable "x" determines the base number of which 30 is 75%

$x = \frac {100 * 30} {75}$

$x=40$

Thus, 30 represents 75% of 40.

Answer:

40
