Answer: 4.4 hours


Step-by-step explanation:

Since Time taken by Ronny=2.75 is nearest to 2.8

Time taken by older brother=1.18 is nearest to 1.2

Time taken by younger brother=0.43 is nearest to 0.4

Hence after round off the time taken by all of the boys to the nearest tenth

The total time taken by all brothers to read=2.8+1.2+0.4 = 4.4 hours

Thus, the three brothers read for 4.4 hours yesterday altogether.
