9.9 is what percent of 6.2 - 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 6.2 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 6.2, so we can write it down as 100%=6.2.
4. We know, that x% equals 9.9 of the output value, so we can write it down as x%=9.9.
5. Now we have two simple equations:
1) 100%=6.2
2) x%=9.9
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%=6.2/9.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.9 is what percent of 6.2

100%/x%=6.2/9.9
(100/x)*x=(6.2/9.9)*x       - we multiply both sides of the equation by x
100=0.62626262626263*x       - we divide both sides of the equation by (0.62626262626263) to get x
100/0.62626262626263=x
159.67741935484=x
x=159.67741935484

now we have:
9.9 is 159.67741935484% of 6.2
