163/279 can also be written as 1.63/2.79 = 1.6/2.8.
Here consider 2.79 as 2.8.
1.6*2 = 3.2 But 2.8<3.2 so1.6/2.8 is >0.5 around 0.57.

Explain
489.1375 = 489 (after decimal number is less than 5).
0.0483 = 0.05 (after decimal number is 8 this is greater than 5 so add the 1 because 0.04+1=0.05).
So all numbers are same method apply.
