42.6 is what percent of 350 - 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 350 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 350, so we can write it down as 100%=350.
4. We know, that x% equals 42.6 of the output value, so we can write it down as x%=42.6.
5. Now we have two simple equations:
1) 100%=350
2) x%=42.6
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%=350/42.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.6 is what percent of 350

100%/x%=350/42.6
(100/x)*x=(350/42.6)*x       - we multiply both sides of the equation by x
100=8.2159624413146*x       - we divide both sides of the equation by (8.2159624413146) to get x
100/8.2159624413146=x
12.171428571429=x
x=12.171428571429

now we have:
42.6 is 12.171428571429% of 350
