99 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 99 of the output value, so we can write it down as x%=99.
5. Now we have two simple equations:
1) 100%=473
2) x%=99
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%=473/99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 99 is what percent of 473

100%/x%=473/99
(100/x)*x=(473/99)*x       - we multiply both sides of the equation by x
100=4.7777777777778*x       - we divide both sides of the equation by (4.7777777777778) to get x
100/4.7777777777778=x
20.93023255814=x
x=20.93023255814

now we have:
99 is 20.93023255814% of 473
