191.88 is what percent of 399.75 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 399.75 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 399.75, so we can write it down as 100%=399.75.
4. We know, that x% equals 191.88 of the output value, so we can write it down as x%=191.88.
5. Now we have two simple equations:
1) 100%=399.75
2) x%=191.88
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=399.75/191.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 191.88 is what percent of 399.75

100%/x%=399.75/191.88
(100/x)*x=(399.75/191.88)*x       - we multiply both sides of the equation by x
100=2.0833333333333*x       - we divide both sides of the equation by (2.0833333333333) to get x
100/2.0833333333333=x
48=x
x=48

now we have:
191.88 is 48% of 399.75
