77.4 is what percent of 93 - 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 93 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 93, so we can write it down as 100%=93.
4. We know, that x% equals 77.4 of the output value, so we can write it down as x%=77.4.
5. Now we have two simple equations:
1) 100%=93
2) x%=77.4
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%=93/77.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77.4 is what percent of 93

100%/x%=93/77.4
(100/x)*x=(93/77.4)*x       - we multiply both sides of the equation by x
100=1.2015503875969*x       - we divide both sides of the equation by (1.2015503875969) to get x
100/1.2015503875969=x
83.225806451613=x
x=83.225806451613

now we have:
77.4 is 83.225806451613% of 93
