70 is what percent of 20858 - 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 20858 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 20858, so we can write it down as 100%=20858.
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%=20858
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%=20858/70
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 20858

100%/x%=20858/70
(100/x)*x=(20858/70)*x       - we multiply both sides of the equation by x
100=297.97142857143*x       - we divide both sides of the equation by (297.97142857143) to get x
100/297.97142857143=x
0.33560264646658=x
x=0.33560264646658

now we have:
70 is 0.33560264646658% of 20858
