What is 380 percent of 77.5 - 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 77.5 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 77.5 is 100%, so we can write it down as 77.5=100%.
4. We know, that x is 380% of the output value, so we can write it down as x=380%.
5. Now we have two simple equations:
1) 77.5=100%
2) x=380%
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:
77.5/x=100%/380%
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 380% of 77.5

77.5/x=100/380
(77.5/x)*x=(100/380)*x       - we multiply both sides of the equation by x
77.5=0.26315789473684*x       - we divide both sides of the equation by (0.26315789473684) to get x
77.5/0.26315789473684=x
294.5=x
x=294.5

now we have:
380% of 77.5=294.5
