If 9 is 25% of a number, using this knowledge, we can solve this problem using an equation. First, we must convert 25% to its decimal equivalent, by dividing by 100 (moving the decimal place two places to the left). 25% = 25/100 = 0.25.
Knowing this, we can construct our equation and let our unknown value be represented by the variable x.
9 = 0.25x
To solve our equation, we must divide both sides by 0.25 to get the variable x alone on the right side of the equation.
x = 36
Therefore, your answer is 36 (9 is 25% of 36).
Hope this helps!
