Question

Which is the best estimate for the sum 2/9+10/11? * O A. 0 + 0 = 0 OB. 1/2 + 1/2=1 O C. 1 + 1 = 2 O D. 0 + 1 = 1 Please explain the process of how you at your answer

Answer 1

`(2)/(9)\approx0`

this is because 9 is bigger than 2 almost 4 times, so the answer of the division must be close to 0.

now on the other side

`(10)/(11)\approx1`

10 is still smaller than 11 but the difference is small causing that the division be aroun 0.9 or 1.

when you add the estimates together you obtain

`\begin{gathered} (2)/(9)+(10)/(11)=\text{?} \\ 0+1=1 \end{gathered}`
