8.11 is what percent of 157.4 - 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 157.4 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 157.4, so we can write it down as 100%=157.4.
4. We know, that x% equals 8.11 of the output value, so we can write it down as x%=8.11.
5. Now we have two simple equations:
1) 100%=157.4
2) x%=8.11
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%=157.4/8.11
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.11 is what percent of 157.4

100%/x%=157.4/8.11
(100/x)*x=(157.4/8.11)*x       - we multiply both sides of the equation by x
100=19.40813810111*x       - we divide both sides of the equation by (19.40813810111) to get x
100/19.40813810111=x
5.1524777636595=x
x=5.1524777636595

now we have:
8.11 is 5.1524777636595% of 157.4
