86 is what percent of 342 - 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 342 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 342, so we can write it down as 100%=342.
4. We know, that x% equals 86 of the output value, so we can write it down as x%=86.
5. Now we have two simple equations:
1) 100%=342
2) x%=86
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%=342/86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 86 is what percent of 342

100%/x%=342/86
(100/x)*x=(342/86)*x       - we multiply both sides of the equation by x
100=3.9767441860465*x       - we divide both sides of the equation by (3.9767441860465) to get x
100/3.9767441860465=x
25.146198830409=x
x=25.146198830409

now we have:
86 is 25.146198830409% of 342
