71 is what percent of 1138 - 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 1138 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 1138, so we can write it down as 100%=1138.
4. We know, that x% equals 71 of the output value, so we can write it down as x%=71.
5. Now we have two simple equations:
1) 100%=1138
2) x%=71
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%=1138/71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 71 is what percent of 1138

100%/x%=1138/71
(100/x)*x=(1138/71)*x       - we multiply both sides of the equation by x
100=16.028169014085*x       - we divide both sides of the equation by (16.028169014085) to get x
100/16.028169014085=x
6.2390158172232=x
x=6.2390158172232

now we have:
71 is 6.2390158172232% of 1138
