1.98 is what percent of 10 - 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 10 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 10, so we can write it down as 100%=10.
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%=10
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%=10/1.98
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 10

100%/x%=10/1.98
(100/x)*x=(10/1.98)*x       - we multiply both sides of the equation by x
100=5.05050505051*x       - we divide both sides of the equation by (5.05050505051) to get x
100/5.05050505051=x
19.8=x
x=19.8

now we have:
1.98 is 19.8% of 10
