What is 30.4 percent of 31.7 - 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 31.7 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 31.7 is 100%, so we can write it down as 31.7=100%.
4. We know, that x is 30.4% of the output value, so we can write it down as x=30.4%.
5. Now we have two simple equations:
1) 31.7=100%
2) x=30.4%
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:
31.7/x=100%/30.4%
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 30.4% of 31.7

31.7/x=100/30.4
(31.7/x)*x=(100/30.4)*x       - we multiply both sides of the equation by x
31.7=3.2894736842105*x       - we divide both sides of the equation by (3.2894736842105) to get x
31.7/3.2894736842105=x
9.6368=x
x=9.6368

now we have:
30.4% of 31.7=9.6368
