893.7 is what percent of 900 - 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 900 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 900, so we can write it down as 100%=900.
4. We know, that x% equals 893.7 of the output value, so we can write it down as x%=893.7.
5. Now we have two simple equations:
1) 100%=900
2) x%=893.7
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%=900/893.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 893.7 is what percent of 900

100%/x%=900/893.7
(100/x)*x=(900/893.7)*x       - we multiply both sides of the equation by x
100=1.0070493454179*x       - we divide both sides of the equation by (1.0070493454179) to get x
100/1.0070493454179=x
99.3=x
x=99.3

now we have:
893.7 is 99.3% of 900
