74.5 is what percent of 340 - 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 340 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 340, so we can write it down as 100%=340.
4. We know, that x% equals 74.5 of the output value, so we can write it down as x%=74.5.
5. Now we have two simple equations:
1) 100%=340
2) x%=74.5
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%=340/74.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74.5 is what percent of 340

100%/x%=340/74.5
(100/x)*x=(340/74.5)*x       - we multiply both sides of the equation by x
100=4.5637583892617*x       - we divide both sides of the equation by (4.5637583892617) to get x
100/4.5637583892617=x
21.911764705882=x
x=21.911764705882

now we have:
74.5 is 21.911764705882% of 340
