To solve this problem, we are going to set up an equation and let our unknown value be represented by the variable x. First, we must convert 25% into its decimal equivalent by dividing 25/100.
25/100 = 0.25
We should keep in mind that when we use the word “of” in math, it represents multiplication. This means that our equation should be set up with 2/3 multiplied by 27 on the left side equal to 0.25 times x on the right side, as modeled below:
(2/3)(27)=0.25x
To simplify this equation, we should perform the multiplication on the left side of the equation.
18 = 0.25x
Finally, we should divide both sides of the equation by 0.25 in order to isolate the variable x on the right side of the equation.
x = 72
Therefore, your answer and unknown number is 72.
Hope this helps!
