What is 510 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 510% of the output value, so we can write it down as x=510%.
5. Now we have two simple equations:
1) 388=100%
2) x=510%
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%/510%
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 510% of 388

388/x=100/510
(388/x)*x=(100/510)*x       - we multiply both sides of the equation by x
388=0.19607843137255*x       - we divide both sides of the equation by (0.19607843137255) to get x
388/0.19607843137255=x
1978.8=x
x=1978.8

now we have:
510% of 388=1978.8
