7.1 is what percent of 19.2 - 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 19.2 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 19.2, so we can write it down as 100%=19.2.
4. We know, that x% equals 7.1 of the output value, so we can write it down as x%=7.1.
5. Now we have two simple equations:
1) 100%=19.2
2) x%=7.1
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%=19.2/7.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.1 is what percent of 19.2

100%/x%=19.2/7.1
(100/x)*x=(19.2/7.1)*x       - we multiply both sides of the equation by x
100=2.7042253521127*x       - we divide both sides of the equation by (2.7042253521127) to get x
100/2.7042253521127=x
36.979166666667=x
x=36.979166666667

now we have:
7.1 is 36.979166666667% of 19.2
