16.98 is what percent of 84.9 - 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 84.9 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 84.9, so we can write it down as 100%=84.9.
4. We know, that x% equals 16.98 of the output value, so we can write it down as x%=16.98.
5. Now we have two simple equations:
1) 100%=84.9
2) x%=16.98
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%=84.9/16.98
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.98 is what percent of 84.9

100%/x%=84.9/16.98
(100/x)*x=(84.9/16.98)*x       - we multiply both sides of the equation by x
100=5*x       - we divide both sides of the equation by (5) to get x
100/5=x
20=x
x=20

now we have:
16.98 is 20% of 84.9
