32 is what percent of 686 - 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 686 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 686, so we can write it down as 100%=686.
4. We know, that x% equals 32 of the output value, so we can write it down as x%=32.
5. Now we have two simple equations:
1) 100%=686
2) x%=32
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%=686/32
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 32 is what percent of 686

100%/x%=686/32
(100/x)*x=(686/32)*x       - we multiply both sides of the equation by x
100=21.4375*x       - we divide both sides of the equation by (21.4375) to get x
100/21.4375=x
4.66472303207=x
x=4.66472303207

now we have:
32 is 4.66472303207% of 686
