74 is what percent of 842 - 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 842 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 842, so we can write it down as 100%=842.
4. We know, that x% equals 74 of the output value, so we can write it down as x%=74.
5. Now we have two simple equations:
1) 100%=842
2) x%=74
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%=842/74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74 is what percent of 842

100%/x%=842/74
(100/x)*x=(842/74)*x       - we multiply both sides of the equation by x
100=11.378378378378*x       - we divide both sides of the equation by (11.378378378378) to get x
100/11.378378378378=x
8.7885985748219=x
x=8.7885985748219

now we have:
74 is 8.7885985748219% of 842
