45 is what percent of 473 - 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 473 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 473, so we can write it down as 100%=473.
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%=473
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%=473/45
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 473

100%/x%=473/45
(100/x)*x=(473/45)*x       - we multiply both sides of the equation by x
100=10.511111111111*x       - we divide both sides of the equation by (10.511111111111) to get x
100/10.511111111111=x
9.5137420718816=x
x=9.5137420718816

now we have:
45 is 9.5137420718816% of 473
