Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
[tex]-14\dfrac{1}{9}\times -2\dfrac{9}{10}[/tex]
We first round off the elements one by one :
[tex]14\dfrac{1}{9}\\\\=14+0.11\\\\=14.11\\\\\approx 14[/tex]
Similarly,
[tex]2\dfrac{9}{10}\\\\=2+0.9\\\\=2.9\\\\\approx 3[/tex]
So, Best estimate would be
[tex]-14\times -3\\\\=42[/tex]
Hence, Option 'D' is correct.
