30.7 is what percent of 1962.9 - 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 1962.9 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 1962.9, so we can write it down as 100%=1962.9.
4. We know, that x% equals 30.7 of the output value, so we can write it down as x%=30.7.
5. Now we have two simple equations:
1) 100%=1962.9
2) x%=30.7
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%=1962.9/30.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.7 is what percent of 1962.9

100%/x%=1962.9/30.7
(100/x)*x=(1962.9/30.7)*x       - we multiply both sides of the equation by x
100=63.938110749186*x       - we divide both sides of the equation by (63.938110749186) to get x
100/63.938110749186=x
1.5640124305874=x
x=1.5640124305874

now we have:
30.7 is 1.5640124305874% of 1962.9
