70 is what percent of 40600 - 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 40600 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 40600, so we can write it down as 100%=40600.
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%=40600
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%=40600/70
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 40600

100%/x%=40600/70
(100/x)*x=(40600/70)*x       - we multiply both sides of the equation by x
100=580*x       - we divide both sides of the equation by (580) to get x
100/580=x
0.17241379310345=x
x=0.17241379310345

now we have:
70 is 0.17241379310345% of 40600
