71 is what percent of 1040 - 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 1040 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 1040, so we can write it down as 100%=1040.
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%=1040
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%=1040/71
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 1040

100%/x%=1040/71
(100/x)*x=(1040/71)*x       - we multiply both sides of the equation by x
100=14.647887323944*x       - we divide both sides of the equation by (14.647887323944) to get x
100/14.647887323944=x
6.8269230769231=x
x=6.8269230769231

now we have:
71 is 6.8269230769231% of 1040
