138.4 is what percent of 6964.9 - 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 6964.9 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 6964.9, so we can write it down as 100%=6964.9.
4. We know, that x% equals 138.4 of the output value, so we can write it down as x%=138.4.
5. Now we have two simple equations:
1) 100%=6964.9
2) x%=138.4
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%=6964.9/138.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 138.4 is what percent of 6964.9

100%/x%=6964.9/138.4
(100/x)*x=(6964.9/138.4)*x       - we multiply both sides of the equation by x
100=50.324421965318*x       - we divide both sides of the equation by (50.324421965318) to get x
100/50.324421965318=x
1.9871067782739=x
x=1.9871067782739

now we have:
138.4 is 1.9871067782739% of 6964.9
