123.7 is what percent of 177 - 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 177 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 177, so we can write it down as 100%=177.
4. We know, that x% equals 123.7 of the output value, so we can write it down as x%=123.7.
5. Now we have two simple equations:
1) 100%=177
2) x%=123.7
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%=177/123.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 123.7 is what percent of 177

100%/x%=177/123.7
(100/x)*x=(177/123.7)*x       - we multiply both sides of the equation by x
100=1.4308811641067*x       - we divide both sides of the equation by (1.4308811641067) to get x
100/1.4308811641067=x
69.887005649718=x
x=69.887005649718

now we have:
123.7 is 69.887005649718% of 177
