17.7 is what percent of 52.2 - 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 52.2 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 52.2, so we can write it down as 100%=52.2.
4. We know, that x% equals 17.7 of the output value, so we can write it down as x%=17.7.
5. Now we have two simple equations:
1) 100%=52.2
2) x%=17.7
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%=52.2/17.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.7 is what percent of 52.2

100%/x%=52.2/17.7
(100/x)*x=(52.2/17.7)*x       - we multiply both sides of the equation by x
100=2.9491525423729*x       - we divide both sides of the equation by (2.9491525423729) to get x
100/2.9491525423729=x
33.908045977011=x
x=33.908045977011

now we have:
17.7 is 33.908045977011% of 52.2
