1.9 is what percent of 0.1 - 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 0.1 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 0.1, so we can write it down as 100%=0.1.
4. We know, that x% equals 1.9 of the output value, so we can write it down as x%=1.9.
5. Now we have two simple equations:
1) 100%=0.1
2) x%=1.9
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%=0.1/1.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.9 is what percent of 0.1

100%/x%=0.1/1.9
(100/x)*x=(0.1/1.9)*x       - we multiply both sides of the equation by x
100=0.052631578947368*x       - we divide both sides of the equation by (0.052631578947368) to get x
100/0.052631578947368=x
1900=x
x=1900

now we have:
1.9 is 1900% of 0.1
