71.8 is what percent of 19 - 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 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, so we can write it down as 100%=19.
4. We know, that x% equals 71.8 of the output value, so we can write it down as x%=71.8.
5. Now we have two simple equations:
1) 100%=19
2) x%=71.8
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%=19/71.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 71.8 is what percent of 19

100%/x%=19/71.8
(100/x)*x=(19/71.8)*x       - we multiply both sides of the equation by x
100=0.26462395543175*x       - we divide both sides of the equation by (0.26462395543175) to get x
100/0.26462395543175=x
377.89473684211=x
x=377.89473684211

now we have:
71.8 is 377.89473684211% of 19
