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

a. 0x8

b. 1x10

c. 7x8

d. 1x8

Option D -

Step-by-step explanation:

To find : Which expression is the best estimate of the product of and ?

Solution :

We estimate the number individually,

Estimate the number we get 0.875≈1.

Estimate the number we get 8.1≈8.

The product of and is

Therefore, option D is correct.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
