Answer:
7
Step-by-step explanation:
what number is 28% of 25
Is means equals and of means multiply
N = 28% of 25
Change to decimal form
N = .28* 25
N =7
We assume, that the number 25 is 100% - because it's the output value of the task.
25/x=100/28
(25/x)*x =(100/28)*x - we multiply both sides of the equation by x
25 = 3.57142857143*x - we divide both sides of the equation by (3.57142857143) to get x
25/3.57142857143 = x
x=7
