142.74 is what percent of 71.37 - 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 71.37 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 71.37, so we can write it down as 100%=71.37.
4. We know, that x% equals 142.74 of the output value, so we can write it down as x%=142.74.
5. Now we have two simple equations:
1) 100%=71.37
2) x%=142.74
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%=71.37/142.74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 142.74 is what percent of 71.37

100%/x%=71.37/142.74
(100/x)*x=(71.37/142.74)*x       - we multiply both sides of the equation by x
100=0.5*x       - we divide both sides of the equation by (0.5) to get x
100/0.5=x
200=x
x=200

now we have:
142.74 is 200% of 71.37
