What is 790 percent of 840 - 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 840 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 840 is 100%, so we can write it down as 840=100%.
4. We know, that x is 790% of the output value, so we can write it down as x=790%.
5. Now we have two simple equations:
1) 840=100%
2) x=790%
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:
840/x=100%/790%
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 790% of 840

840/x=100/790
(840/x)*x=(100/790)*x       - we multiply both sides of the equation by x
840=0.12658227848101*x       - we divide both sides of the equation by (0.12658227848101) to get x
840/0.12658227848101=x
6636=x
x=6636

now we have:
790% of 840=6636
