101.9 is what percent of 101.9 - 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 101.9 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 101.9, so we can write it down as 100%=101.9.
4. We know, that x% equals 101.9 of the output value, so we can write it down as x%=101.9.
5. Now we have two simple equations:
1) 100%=101.9
2) x%=101.9
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%=101.9/101.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 101.9 is what percent of 101.9

100%/x%=101.9/101.9
(100/x)*x=(101.9/101.9)*x       - we multiply both sides of the equation by x
100=1*x       - we divide both sides of the equation by (1) to get x
100/1=x
100=x
x=100

now we have:
101.9 is 100% of 101.9
