What is 77.6 percent of 388 - 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 388 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 388 is 100%, so we can write it down as 388=100%.
4. We know, that x is 77.6% of the output value, so we can write it down as x=77.6%.
5. Now we have two simple equations:
1) 388=100%
2) x=77.6%
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:
388/x=100%/77.6%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 77.6% of 388

388/x=100/77.6
(388/x)*x=(100/77.6)*x       - we multiply both sides of the equation by x
388=1.2886597938144*x       - we divide both sides of the equation by (1.2886597938144) to get x
388/1.2886597938144=x
301.088=x
x=301.088

now we have:
77.6% of 388=301.088
