1.98 is what percent of 9.88 - 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 9.88 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 9.88, so we can write it down as 100%=9.88.
4. We know, that x% equals 1.98 of the output value, so we can write it down as x%=1.98.
5. Now we have two simple equations:
1) 100%=9.88
2) x%=1.98
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%=9.88/1.98
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.98 is what percent of 9.88

100%/x%=9.88/1.98
(100/x)*x=(9.88/1.98)*x       - we multiply both sides of the equation by x
100=4.989898989899*x       - we divide both sides of the equation by (4.989898989899) to get x
100/4.989898989899=x
20.04048582996=x
x=20.04048582996

now we have:
1.98 is 20.04048582996% of 9.88
