13.4 is what percent of 842 - 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 842 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 842, so we can write it down as 100%=842.
4. We know, that x% equals 13.4 of the output value, so we can write it down as x%=13.4.
5. Now we have two simple equations:
1) 100%=842
2) x%=13.4
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%=842/13.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.4 is what percent of 842

100%/x%=842/13.4
(100/x)*x=(842/13.4)*x       - we multiply both sides of the equation by x
100=62.835820895522*x       - we divide both sides of the equation by (62.835820895522) to get x
100/62.835820895522=x
1.5914489311164=x
x=1.5914489311164

now we have:
13.4 is 1.5914489311164% of 842
