Ronny read for 2.75 hours yesterday his older brother read for 1.18 hours and his younger brother read for 0.43 hours.

round each time to the nearest tenth of an hour.

about how long did the three brothers read yesterday altogether?

a.
about 1.2 hours

b.
about 1.6 hours

c.
about 4.2 hours

d.
about 4.4 hours

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.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
