What is 1.71 percent of 391 - 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 391 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 391 is 100%, so we can write it down as 391=100%.
4. We know, that x is 1.71% of the output value, so we can write it down as x=1.71%.
5. Now we have two simple equations:
1) 391=100%
2) x=1.71%
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:
391/x=100%/1.71%
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 1.71% of 391

391/x=100/1.71
(391/x)*x=(100/1.71)*x       - we multiply both sides of the equation by x
391=58.479532163743*x       - we divide both sides of the equation by (58.479532163743) to get x
391/58.479532163743=x
6.6861=x
x=6.6861

now we have:
1.71% of 391=6.6861
