What is 3.5 percent of 834.21 - 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 834.21 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 834.21 is 100%, so we can write it down as 834.21=100%.
4. We know, that x is 3.5% of the output value, so we can write it down as x=3.5%.
5. Now we have two simple equations:
1) 834.21=100%
2) x=3.5%
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:
834.21/x=100%/3.5%
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 3.5% of 834.21

834.21/x=100/3.5
(834.21/x)*x=(100/3.5)*x       - we multiply both sides of the equation by x
834.21=28.571428571429*x       - we divide both sides of the equation by (28.571428571429) to get x
834.21/28.571428571429=x
29.19735=x
x=29.19735

now we have:
3.5% of 834.21=29.19735
