70 is what percent of 2400 - 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 2400 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 2400, so we can write it down as 100%=2400.
4. We know, that x% equals 70 of the output value, so we can write it down as x%=70.
5. Now we have two simple equations:
1) 100%=2400
2) x%=70
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%=2400/70
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70 is what percent of 2400

100%/x%=2400/70
(100/x)*x=(2400/70)*x       - we multiply both sides of the equation by x
100=34.285714285714*x       - we divide both sides of the equation by (34.285714285714) to get x
100/34.285714285714=x
2.9166666666667=x
x=2.9166666666667

now we have:
70 is 2.9166666666667% of 2400
