15.99 is what percent of 153 - 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 153 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 153, so we can write it down as 100%=153.
4. We know, that x% equals 15.99 of the output value, so we can write it down as x%=15.99.
5. Now we have two simple equations:
1) 100%=153
2) x%=15.99
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%=153/15.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.99 is what percent of 153

100%/x%=153/15.99
(100/x)*x=(153/15.99)*x       - we multiply both sides of the equation by x
100=9.5684803001876*x       - we divide both sides of the equation by (9.5684803001876) to get x
100/9.5684803001876=x
10.450980392157=x
x=10.450980392157

now we have:
15.99 is 10.450980392157% of 153
