17.55 is what percent of 7.02 - 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 7.02 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 7.02, so we can write it down as 100%=7.02.
4. We know, that x% equals 17.55 of the output value, so we can write it down as x%=17.55.
5. Now we have two simple equations:
1) 100%=7.02
2) x%=17.55
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%=7.02/17.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.55 is what percent of 7.02

100%/x%=7.02/17.55
(100/x)*x=(7.02/17.55)*x       - we multiply both sides of the equation by x
100=0.4*x       - we divide both sides of the equation by (0.4) to get x
100/0.4=x
250=x
x=250

now we have:
17.55 is 250% of 7.02
