69 is what percent of 679 - 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 679 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 679, so we can write it down as 100%=679.
4. We know, that x% equals 69 of the output value, so we can write it down as x%=69.
5. Now we have two simple equations:
1) 100%=679
2) x%=69
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%=679/69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69 is what percent of 679

100%/x%=679/69
(100/x)*x=(679/69)*x       - we multiply both sides of the equation by x
100=9.8405797101449*x       - we divide both sides of the equation by (9.8405797101449) to get x
100/9.8405797101449=x
10.162002945508=x
x=10.162002945508

now we have:
69 is 10.162002945508% of 679
