68 is what percent of 1687 - 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 1687 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 1687, so we can write it down as 100%=1687.
4. We know, that x% equals 68 of the output value, so we can write it down as x%=68.
5. Now we have two simple equations:
1) 100%=1687
2) x%=68
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%=1687/68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 68 is what percent of 1687

100%/x%=1687/68
(100/x)*x=(1687/68)*x       - we multiply both sides of the equation by x
100=24.808823529412*x       - we divide both sides of the equation by (24.808823529412) to get x
100/24.808823529412=x
4.0308239478364=x
x=4.0308239478364

now we have:
68 is 4.0308239478364% of 1687
