Question

Brad used the compatible numbers 810/90 for an estimate. Which quotient might he be finding? A. 5380 divided by 59 B. 822 divided by 91 C. 277 divided by 31 D. 84 divided by 9

Answer 1

The quotient Brad might be finding using the compatible numbers 810/90 is option D, 84 divided by 9.

Step-by-step explanation:

Brad used the compatible numbers 810/90, which simplify to 9, as an estimate. This suggests he's likely finding a quotient that involves dividing a number by 9. Among the options, only option D, 84 divided by 9, aligns with this estimation strategy.

Now, let's break down each option:

A.
`\(5380 / 59\)` does not involve a divisor of 9.

B.
`\(822 / 91\)` does not involve a divisor of 9.

C.
`\(277 / 31\)` does not involve a divisor of 9.

D.
`\(84 / 9\)` perfectly aligns with the compatible numbers Brad used for estimation (810/90), indicating that this is the quotient he might be finding.

In summary, by analyzing the options and recognizing the use of compatible numbers, it becomes evident that option D is the most likely quotient that Brad is estimating using the given strategy.
