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.

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
