Which is the best estimate for the sum of 2 /9 + 10 /11 ? a. 0 + 0 = 0 b. 1/2 + 1/2 = 1 c. 1 + 1 = 2 d. 0 + 1 = 1

The best estimate for the sum of 2/9 and 10/11 is;

Option D; 0 + 1 = 1.

    Estimate simply means approximating the number to the nearest whole number.

Now we have 2/9 and 10/11.

Thus;

2/9 is closer to 0 than 0.5 and as such we will estimate it as 0.

Similarly, 10/11 is closer to 1 than 0.5 and so we will estimate it as 1.

Therefore the sum of their estimates gives;

0 + 1 = 1

In conclusion, the best estimate for the sum of 2/9 and 10/11 is 0 + 1 = 1.
