84 is what percent of 1297 - 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 1297 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 1297, so we can write it down as 100%=1297.
4. We know, that x% equals 84 of the output value, so we can write it down as x%=84.
5. Now we have two simple equations:
1) 100%=1297
2) x%=84
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%=1297/84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 84 is what percent of 1297

100%/x%=1297/84
(100/x)*x=(1297/84)*x       - we multiply both sides of the equation by x
100=15.440476190476*x       - we divide both sides of the equation by (15.440476190476) to get x
100/15.440476190476=x
6.4764841942945=x
x=6.4764841942945

now we have:
84 is 6.4764841942945% of 1297
