342.5 is what percent of 1380.4 - 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 1380.4 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 1380.4, so we can write it down as 100%=1380.4.
4. We know, that x% equals 342.5 of the output value, so we can write it down as x%=342.5.
5. Now we have two simple equations:
1) 100%=1380.4
2) x%=342.5
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%=1380.4/342.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 342.5 is what percent of 1380.4

100%/x%=1380.4/342.5
(100/x)*x=(1380.4/342.5)*x       - we multiply both sides of the equation by x
100=4.0303649635036*x       - we divide both sides of the equation by (4.0303649635036) to get x
100/4.0303649635036=x
24.81164879745=x
x=24.81164879745

now we have:
342.5 is 24.81164879745% of 1380.4
