Answer:
<h3>975</h3>
Step-by-step explanation:
Formula = <u>Number</u><u> </u><u> </u><u>×</u><u> </u><u>1</u><u>0</u><u>0</u> = <u>3</u><u>9</u><u> </u><u>×</u><u> </u><u> </u><u>1</u><u>0</u><u>0</u>
Percent 4
Following shows the steps on how to derive this formula
<u>Step</u><u> </u><u>1</u><u> </u><u>:</u> if 4% of a number is 39, then what is 100% of the number ? Setup the equation.
<u> </u><u> </u><u> </u><u>3</u><u>9</u><u> </u><u> </u><u> </u> = <u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>Y</u><u> </u><u> </u><u> </u><u> </u>
4% 100 %
<u>Step</u><u> </u><u>2</u><u> </u><u>:</u> Solve for Y
Using cross multiplication of two fractions , we get
4Y = 39 × 100
4Y = <u>3</u><u>9</u><u>0</u><u>0</u> = 975
