0.19 is what percent of 0.28 - 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 0.28 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 0.28, so we can write it down as 100%=0.28.
4. We know, that x% equals 0.19 of the output value, so we can write it down as x%=0.19.
5. Now we have two simple equations:
1) 100%=0.28
2) x%=0.19
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%=0.28/0.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.19 is what percent of 0.28

100%/x%=0.28/0.19
(100/x)*x=(0.28/0.19)*x       - we multiply both sides of the equation by x
100=1.4736842105263*x       - we divide both sides of the equation by (1.4736842105263) to get x
100/1.4736842105263=x
67.857142857143=x
x=67.857142857143

now we have:
0.19 is 67.857142857143% of 0.28
