69 is what percent of 1245 - 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 1245 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 1245, so we can write it down as 100%=1245.
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%=1245
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%=1245/69
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 1245

100%/x%=1245/69
(100/x)*x=(1245/69)*x       - we multiply both sides of the equation by x
100=18.04347826087*x       - we divide both sides of the equation by (18.04347826087) to get x
100/18.04347826087=x
5.5421686746988=x
x=5.5421686746988

now we have:
69 is 5.5421686746988% of 1245
