Answer:
42
Step-by-step explanation:
We want to find the the best estimate for
[tex] - 14 \frac{1}{9} \times - 2 \frac{9}{10} [/tex]
We round each number to the nearest whole number to get:
[tex] - 14 \times - 3[/tex]
Recall that negative times negative gives positive result
[tex]14 \times 3[/tex]
This finally gives
[tex]42[/tex]
Therefore the best estimate is 42
