45 is what percent of 763 - 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 763 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 763, so we can write it down as 100%=763.
4. We know, that x% equals 45 of the output value, so we can write it down as x%=45.
5. Now we have two simple equations:
1) 100%=763
2) x%=45
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%=763/45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 45 is what percent of 763

100%/x%=763/45
(100/x)*x=(763/45)*x       - we multiply both sides of the equation by x
100=16.955555555556*x       - we divide both sides of the equation by (16.955555555556) to get x
100/16.955555555556=x
5.8977719528178=x
x=5.8977719528178

now we have:
45 is 5.8977719528178% of 763
