151.2 is what percent of 1551.6 - 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 1551.6 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 1551.6, so we can write it down as 100%=1551.6.
4. We know, that x% equals 151.2 of the output value, so we can write it down as x%=151.2.
5. Now we have two simple equations:
1) 100%=1551.6
2) x%=151.2
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%=1551.6/151.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 151.2 is what percent of 1551.6

100%/x%=1551.6/151.2
(100/x)*x=(1551.6/151.2)*x       - we multiply both sides of the equation by x
100=10.261904761905*x       - we divide both sides of the equation by (10.261904761905) to get x
100/10.261904761905=x
9.7447795823666=x
x=9.7447795823666

now we have:
151.2 is 9.7447795823666% of 1551.6
