97 is what percent of 399.4 - 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 399.4 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 399.4, so we can write it down as 100%=399.4.
4. We know, that x% equals 97 of the output value, so we can write it down as x%=97.
5. Now we have two simple equations:
1) 100%=399.4
2) x%=97
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%=399.4/97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 97 is what percent of 399.4

100%/x%=399.4/97
(100/x)*x=(399.4/97)*x       - we multiply both sides of the equation by x
100=4.1175257731959*x       - we divide both sides of the equation by (4.1175257731959) to get x
100/4.1175257731959=x
24.286429644467=x
x=24.286429644467

now we have:
97 is 24.286429644467% of 399.4
