121.76 is what percent of 76.1 - 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 76.1 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 76.1, so we can write it down as 100%=76.1.
4. We know, that x% equals 121.76 of the output value, so we can write it down as x%=121.76.
5. Now we have two simple equations:
1) 100%=76.1
2) x%=121.76
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%=76.1/121.76
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 121.76 is what percent of 76.1

100%/x%=76.1/121.76
(100/x)*x=(76.1/121.76)*x       - we multiply both sides of the equation by x
100=0.625*x       - we divide both sides of the equation by (0.625) to get x
100/0.625=x
160=x
x=160

now we have:
121.76 is 160% of 76.1
