139.96 is what percent of 173.8 - 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 173.8 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 173.8, so we can write it down as 100%=173.8.
4. We know, that x% equals 139.96 of the output value, so we can write it down as x%=139.96.
5. Now we have two simple equations:
1) 100%=173.8
2) x%=139.96
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%=173.8/139.96
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 139.96 is what percent of 173.8

100%/x%=173.8/139.96
(100/x)*x=(173.8/139.96)*x       - we multiply both sides of the equation by x
100=1.2417833666762*x       - we divide both sides of the equation by (1.2417833666762) to get x
100/1.2417833666762=x
80.529344073648=x
x=80.529344073648

now we have:
139.96 is 80.529344073648% of 173.8
