8.42 is what percent of 340.6 - 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 340.6 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 340.6, so we can write it down as 100%=340.6.
4. We know, that x% equals 8.42 of the output value, so we can write it down as x%=8.42.
5. Now we have two simple equations:
1) 100%=340.6
2) x%=8.42
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%=340.6/8.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.42 is what percent of 340.6

100%/x%=340.6/8.42
(100/x)*x=(340.6/8.42)*x       - we multiply both sides of the equation by x
100=40.451306413302*x       - we divide both sides of the equation by (40.451306413302) to get x
100/40.451306413302=x
2.4721080446271=x
x=2.4721080446271

now we have:
8.42 is 2.4721080446271% of 340.6
