Question

Consider the expression 635,943 divided by 77. To estimate the quotient to be about 8,000, which approximate values should be used for the dividend and divisor?

A) Dividend: 640,000, Divisor: 80
B) Dividend: 630,000, Divisor: 70
C) Dividend: 630,000, Divisor: 80
D) Dividend: 640,000, Divisor: 70

Answer 1

To estimate the quotient to be about 8,000, the approximate values to use for the dividend and divisor are: Dividend: 640,000, Divisor: 80 (Option A).

Step-by-step explanation:

To estimate the quotient to be about 8,000, we need to choose approximate values for the dividend and divisor that when divided, gives us an answer close to 8,000.

Looking at the options, we can see that the divisor 77 is closest to 80 in option A and closest to 70 in option D. For the dividend, 635,943 is closer to 640,000 in option A and closer to 630,000 in option D.

Therefore, the approximate values to use for the dividend and divisor to estimate the quotient to be about 8,000 are:

Dividend: 640,000, Divisor: 80 (Option A).
