-5 4/9 = 4/9 + 45/9 = -49/9
If we multiply it by 2/2, we got -98/18
If we multiply it by 3/3, we got -147/27
Therefore, we can express -5 4/9 in the forms -49/9, -98/18, and - 147/27
Now, let's represent it in decimal form
45 is the greatest number divisible by 9 that is equal to or less than 49, therefore, we subtract 45 from 49 and add 5 to the solution:
49 | 9
-45 | 5
4 | 9
| 5
Now we multiply 4 by 10, walk one decimal place on the solution and do again the previous steps:
40 | 9
| 5.
40 | 9
-36 | 5.4
4 | 9
| 5.4
Replacing these steps, we find that -49/9 = -5444...
