Question

Which expression is the best estimate of the product of 7/8 and 8 1/10?

Answer 1

Answer:

Option D -$\frac{7}{8}\times 8\frac{1}{10}\approx 1\times 8$

Step-by-step explanation:

To find : Which expression is the best estimate of the product of $\frac{7}{8}$ and $8\frac{1}{10}$?

Solution :

We estimate the number individually,

$\frac{7}{8}=0.875$

Estimate the number we get 0.875≈1.

$8\frac{1}{10}=\frac{81}{10}$

$8\frac{1}{10}=8.1$

Estimate the number we get 8.1≈8.

The product of $\frac{7}{8}$ and $8\frac{1}{10}$ is

$\frac{7}{8}\times 8\frac{1}{10}\approx 1\times 8$

Therefore, option D is correct.
