17.96 is what percent of 287.4 - 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 287.4 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 287.4, so we can write it down as 100%=287.4.
4. We know, that x% equals 17.96 of the output value, so we can write it down as x%=17.96.
5. Now we have two simple equations:
1) 100%=287.4
2) x%=17.96
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%=287.4/17.96
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.96 is what percent of 287.4

100%/x%=287.4/17.96
(100/x)*x=(287.4/17.96)*x       - we multiply both sides of the equation by x
100=16.002227171492*x       - we divide both sides of the equation by (16.002227171492) to get x
100/16.002227171492=x
6.2491301322199=x
x=6.2491301322199

now we have:
17.96 is 6.2491301322199% of 287.4
