70 is what percent of 495 - 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 495 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 495, so we can write it down as 100%=495.
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%=495
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%=495/70
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 495

100%/x%=495/70
(100/x)*x=(495/70)*x       - we multiply both sides of the equation by x
100=7.0714285714286*x       - we divide both sides of the equation by (7.0714285714286) to get x
100/7.0714285714286=x
14.141414141414=x
x=14.141414141414

now we have:
70 is 14.141414141414% of 495
