42.69 is what percent of 61 - 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 61 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 61, so we can write it down as 100%=61.
4. We know, that x% equals 42.69 of the output value, so we can write it down as x%=42.69.
5. Now we have two simple equations:
1) 100%=61
2) x%=42.69
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%=61/42.69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.69 is what percent of 61

100%/x%=61/42.69
(100/x)*x=(61/42.69)*x       - we multiply both sides of the equation by x
100=1.4289060669946*x       - we divide both sides of the equation by (1.4289060669946) to get x
100/1.4289060669946=x
69.983606557377=x
x=69.983606557377

now we have:
42.69 is 69.983606557377% of 61
