74 is what percent of 3150 - 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 3150 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 3150, so we can write it down as 100%=3150.
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%=3150
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%=3150/74
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 3150

100%/x%=3150/74
(100/x)*x=(3150/74)*x       - we multiply both sides of the equation by x
100=42.567567567568*x       - we divide both sides of the equation by (42.567567567568) to get x
100/42.567567567568=x
2.3492063492063=x
x=2.3492063492063

now we have:
74 is 2.3492063492063% of 3150
