74 is what percent of 109.8 - 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 109.8 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 109.8, so we can write it down as 100%=109.8.
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%=109.8
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%=109.8/74
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 109.8

100%/x%=109.8/74
(100/x)*x=(109.8/74)*x       - we multiply both sides of the equation by x
100=1.4837837837838*x       - we divide both sides of the equation by (1.4837837837838) to get x
100/1.4837837837838=x
67.395264116576=x
x=67.395264116576

now we have:
74 is 67.395264116576% of 109.8
