84 is what percent of 1679 - 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 1679 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 100% equals 1679, so we can write it down as 100%=1679.
4. We know, that x% equals 84 of the output value, so we can write it down as x%=84.
5. Now we have two simple equations:
1) 100%=1679
2) x%=84
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:
100%/x%=1679/84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 84 is what percent of 1679

100%/x%=1679/84
(100/x)*x=(1679/84)*x       - we multiply both sides of the equation by x
100=19.988095238095*x       - we divide both sides of the equation by (19.988095238095) to get x
100/19.988095238095=x
5.0029779630733=x
x=5.0029779630733

now we have:
84 is 5.0029779630733% of 1679
