77 is what percent of 67 - 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 67 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 67, so we can write it down as 100%=67.
4. We know, that x% equals 77 of the output value, so we can write it down as x%=77.
5. Now we have two simple equations:
1) 100%=67
2) x%=77
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%=67/77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77 is what percent of 67

100%/x%=67/77
(100/x)*x=(67/77)*x       - we multiply both sides of the equation by x
100=0.87012987012987*x       - we divide both sides of the equation by (0.87012987012987) to get x
100/0.87012987012987=x
114.92537313433=x
x=114.92537313433

now we have:
77 is 114.92537313433% of 67
