2.84 is what percent of 31.5 - 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 31.5 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 31.5, so we can write it down as 100%=31.5.
4. We know, that x% equals 2.84 of the output value, so we can write it down as x%=2.84.
5. Now we have two simple equations:
1) 100%=31.5
2) x%=2.84
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%=31.5/2.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.84 is what percent of 31.5

100%/x%=31.5/2.84
(100/x)*x=(31.5/2.84)*x       - we multiply both sides of the equation by x
100=11.091549295775*x       - we divide both sides of the equation by (11.091549295775) to get x
100/11.091549295775=x
9.015873015873=x
x=9.015873015873

now we have:
2.84 is 9.015873015873% of 31.5
