Answer 1

Answer:

the equation for percentage is this: percentage = 100 * part / whole , and it answers the question "what percentage of 20 is 8". the formula for a part is: part = whole * percentage / 100 , and it answers "what is 40% of 20?"

Answer 2

Answer:

the symbol % represents the fraction $\frac{1}{100}$.

To convert any number to percentage, we divide it with x and multiply with 100, where x is the number of whose percentage the other number is, and put the % symbol after it. If x is not given, we take it as 1.

Eg. 1

x = 1
