What is 677 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 677% of the output value, so we can write it down as x=677%.
5. Now we have two simple equations:
1) 840=100%
2) x=677%
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%/677%
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 677% of 840

840/x=100/677
(840/x)*x=(100/677)*x       - we multiply both sides of the equation by x
840=0.14771048744461*x       - we divide both sides of the equation by (0.14771048744461) to get x
840/0.14771048744461=x
5686.8=x
x=5686.8

now we have:
677% of 840=5686.8
