131.4 is what percent of 1670.66 - 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 1670.66 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 1670.66, so we can write it down as 100%=1670.66.
4. We know, that x% equals 131.4 of the output value, so we can write it down as x%=131.4.
5. Now we have two simple equations:
1) 100%=1670.66
2) x%=131.4
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%=1670.66/131.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 131.4 is what percent of 1670.66

100%/x%=1670.66/131.4
(100/x)*x=(1670.66/131.4)*x       - we multiply both sides of the equation by x
100=12.714307458143*x       - we divide both sides of the equation by (12.714307458143) to get x
100/12.714307458143=x
7.8651550884082=x
x=7.8651550884082

now we have:
131.4 is 7.8651550884082% of 1670.66
