66.3 is what percent of 1020 - 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 1020 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 1020, so we can write it down as 100%=1020.
4. We know, that x% equals 66.3 of the output value, so we can write it down as x%=66.3.
5. Now we have two simple equations:
1) 100%=1020
2) x%=66.3
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%=1020/66.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.3 is what percent of 1020

100%/x%=1020/66.3
(100/x)*x=(1020/66.3)*x       - we multiply both sides of the equation by x
100=15.384615384615*x       - we divide both sides of the equation by (15.384615384615) to get x
100/15.384615384615=x
6.5=x
x=6.5

now we have:
66.3 is 6.5% of 1020
