What is 840 percent of 49 - 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 49 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 49 is 100%, so we can write it down as 49=100%.
4. We know, that x is 840% of the output value, so we can write it down as x=840%.
5. Now we have two simple equations:
1) 49=100%
2) x=840%
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:
49/x=100%/840%
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 840% of 49

49/x=100/840
(49/x)*x=(100/840)*x       - we multiply both sides of the equation by x
49=0.11904761904762*x       - we divide both sides of the equation by (0.11904761904762) to get x
49/0.11904761904762=x
411.6=x
x=411.6

now we have:
840% of 49=411.6
