7.65 is what percent of 123 - 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 123 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 123, so we can write it down as 100%=123.
4. We know, that x% equals 7.65 of the output value, so we can write it down as x%=7.65.
5. Now we have two simple equations:
1) 100%=123
2) x%=7.65
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%=123/7.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.65 is what percent of 123

100%/x%=123/7.65
(100/x)*x=(123/7.65)*x       - we multiply both sides of the equation by x
100=16.078431372549*x       - we divide both sides of the equation by (16.078431372549) to get x
100/16.078431372549=x
6.219512195122=x
x=6.219512195122

now we have:
7.65 is 6.219512195122% of 123
