42 is what percent of 874.961 - 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 874.961 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 874.961, so we can write it down as 100%=874.961.
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%=874.961
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%=874.961/42
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 874.961

100%/x%=874.961/42
(100/x)*x=(874.961/42)*x       - we multiply both sides of the equation by x
100=20.832404761905*x       - we divide both sides of the equation by (20.832404761905) to get x
100/20.832404761905=x
4.8002139523933=x
x=4.8002139523933

now we have:
