0.9 is what percent of 10.6 - 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 10.6 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 10.6, so we can write it down as 100%=10.6.
4. We know, that x% equals 0.9 of the output value, so we can write it down as x%=0.9.
5. Now we have two simple equations:
1) 100%=10.6
2) x%=0.9
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%=10.6/0.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.9 is what percent of 10.6

100%/x%=10.6/0.9
(100/x)*x=(10.6/0.9)*x       - we multiply both sides of the equation by x
100=11.777777777778*x       - we divide both sides of the equation by (11.777777777778) to get x
100/11.777777777778=x
8.4905660377358=x
x=8.4905660377358

now we have:
0.9 is 8.4905660377358% of 10.6
