677.5 is what percent of 695 - 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 695 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 695, so we can write it down as 100%=695.
4. We know, that x% equals 677.5 of the output value, so we can write it down as x%=677.5.
5. Now we have two simple equations:
1) 100%=695
2) x%=677.5
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%=695/677.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 677.5 is what percent of 695

100%/x%=695/677.5
(100/x)*x=(695/677.5)*x       - we multiply both sides of the equation by x
100=1.0258302583026*x       - we divide both sides of the equation by (1.0258302583026) to get x
100/1.0258302583026=x
97.482014388489=x
x=97.482014388489

now we have:
677.5 is 97.482014388489% of 695
