79.8 is what percent of 0.9 - 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 0.9 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 0.9, so we can write it down as 100%=0.9.
4. We know, that x% equals 79.8 of the output value, so we can write it down as x%=79.8.
5. Now we have two simple equations:
1) 100%=0.9
2) x%=79.8
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%=0.9/79.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79.8 is what percent of 0.9

100%/x%=0.9/79.8
(100/x)*x=(0.9/79.8)*x       - we multiply both sides of the equation by x
100=0.011278195488722*x       - we divide both sides of the equation by (0.011278195488722) to get x
100/0.011278195488722=x
8866.6666666667=x
x=8866.6666666667

now we have:
79.8 is 8866.6666666667% of 0.9
