What is 249 percent of 8.42 - 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 8.42 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 8.42 is 100%, so we can write it down as 8.42=100%.
4. We know, that x is 249% of the output value, so we can write it down as x=249%.
5. Now we have two simple equations:
1) 8.42=100%
2) x=249%
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:
8.42/x=100%/249%
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 249% of 8.42

8.42/x=100/249
(8.42/x)*x=(100/249)*x       - we multiply both sides of the equation by x
8.42=0.40160642570281*x       - we divide both sides of the equation by (0.40160642570281) to get x
8.42/0.40160642570281=x
20.9658=x
x=20.9658

now we have:
249% of 8.42=20.9658
