42 is what percent of 6161 - 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 6161 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 6161, so we can write it down as 100%=6161.
4. We know, that x% equals 42 of the output value, so we can write it down as x%=42.
5. Now we have two simple equations:
1) 100%=6161
2) x%=42
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%=6161/42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42 is what percent of 6161

100%/x%=6161/42
(100/x)*x=(6161/42)*x       - we multiply both sides of the equation by x
100=146.69047619048*x       - we divide both sides of the equation by (146.69047619048) to get x
100/146.69047619048=x
0.6817075150138=x
x=0.6817075150138

now we have:
42 is 0.6817075150138% of 6161
