159.9 is what percent of 225 - 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 225 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 225, so we can write it down as 100%=225.
4. We know, that x% equals 159.9 of the output value, so we can write it down as x%=159.9.
5. Now we have two simple equations:
1) 100%=225
2) x%=159.9
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%=225/159.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 159.9 is what percent of 225

100%/x%=225/159.9
(100/x)*x=(225/159.9)*x       - we multiply both sides of the equation by x
100=1.4071294559099*x       - we divide both sides of the equation by (1.4071294559099) to get x
100/1.4071294559099=x
71.066666666667=x
x=71.066666666667

now we have:
159.9 is 71.066666666667% of 225
