53.6 is what percent of 670 - 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 670 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 670, so we can write it down as 100%=670.
4. We know, that x% equals 53.6 of the output value, so we can write it down as x%=53.6.
5. Now we have two simple equations:
1) 100%=670
2) x%=53.6
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%=670/53.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53.6 is what percent of 670

100%/x%=670/53.6
(100/x)*x=(670/53.6)*x       - we multiply both sides of the equation by x
100=12.5*x       - we divide both sides of the equation by (12.5) to get x
100/12.5=x
8=x
x=8

now we have:
53.6 is 8% of 670
