D), I believe it is -42. Correct me if im wrong :}

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.
