Question

Round each mixed number to the nearest whole number and then estimate the difference. 18 9/11 - 8 3/8 10 11 8 9

Answer 1

Answer:

Option (b) = 11 for  difference between $18 \frac{9}{11}$ and $8 \frac{3}{8}$

Explanation:  

For rounding off each mixed number to the nearest whole number.

In this,   $18 \frac{9}{11}$ is rounded off to the nearest whole number 19

$18 \frac{9}{11}=19$

and $8 \frac{3}{8}$ was rounded off to the nearest whole number 8

$8 \frac{3}{8}=8$

$18 \frac{9}{11}-8 \frac{3}{8}$   = 19-8 = 11.  

and the estimated difference was found to be 11  

Answer 2

Answer:

Assuming that the last four numbers are answer choices, your answer would be 11

Step-by-step explanation:

9/11 rounds up to 1, 1 + 18 = 19

3/8 rounds down, so you only have 8 for that one

19 - 8 = 11
