115.3 is what percent of 155 - 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 155 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 155, so we can write it down as 100%=155.
4. We know, that x% equals 115.3 of the output value, so we can write it down as x%=115.3.
5. Now we have two simple equations:
1) 100%=155
2) x%=115.3
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%=155/115.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 115.3 is what percent of 155

100%/x%=155/115.3
(100/x)*x=(155/115.3)*x       - we multiply both sides of the equation by x
100=1.3443191673894*x       - we divide both sides of the equation by (1.3443191673894) to get x
100/1.3443191673894=x
74.387096774194=x
x=74.387096774194

now we have:
115.3 is 74.387096774194% of 155
