31.75 is what percent of 30 - 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 30 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 30, so we can write it down as 100%=30.
4. We know, that x% equals 31.75 of the output value, so we can write it down as x%=31.75.
5. Now we have two simple equations:
1) 100%=30
2) x%=31.75
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%=30/31.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.75 is what percent of 30

100%/x%=30/31.75
(100/x)*x=(30/31.75)*x       - we multiply both sides of the equation by x
100=0.94488188976378*x       - we divide both sides of the equation by (0.94488188976378) to get x
100/0.94488188976378=x
105.83333333333=x
x=105.83333333333

now we have:
31.75 is 105.83333333333% of 30
