19 is what percent of 1.3 - 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 1.3 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 1.3, so we can write it down as 100%=1.3.
4. We know, that x% equals 19 of the output value, so we can write it down as x%=19.
5. Now we have two simple equations:
1) 100%=1.3
2) x%=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%=1.3/19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19 is what percent of 1.3

100%/x%=1.3/19
(100/x)*x=(1.3/19)*x       - we multiply both sides of the equation by x
100=0.068421052631579*x       - we divide both sides of the equation by (0.068421052631579) to get x
100/0.068421052631579=x
1461.5384615385=x
x=1461.5384615385

now we have:
19 is 1461.5384615385% of 1.3
