154.6 is what percent of 209.4 - 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 209.4 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 209.4, so we can write it down as 100%=209.4.
4. We know, that x% equals 154.6 of the output value, so we can write it down as x%=154.6.
5. Now we have two simple equations:
1) 100%=209.4
2) x%=154.6
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%=209.4/154.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 154.6 is what percent of 209.4

100%/x%=209.4/154.6
(100/x)*x=(209.4/154.6)*x       - we multiply both sides of the equation by x
100=1.3544631306598*x       - we divide both sides of the equation by (1.3544631306598) to get x
100/1.3544631306598=x
73.829990448902=x
x=73.829990448902

now we have:
154.6 is 73.829990448902% of 209.4
