Astudents work to solve 2 6/7 / 2/7 is shown below. which of the following statements do you agree with. 2 6/7 / 2/7 = 19/7 / 2/7 = 7/19 x 2/7 = 1/19 x 2/1 = 2/19 a. the only mistake is changing the mixed number to an improper fraction. b. there's a mistake with the multiplicative inverse 2/7 . c. the problem looks correct. d. there's a problem with changing the mixed number to an improper fraction, as well as changing the division problem to multiplication.

D. There's a problem with changing the mixed number to an improper fraction, as well as changing the division problem to multiplication.

Step-by-step explanation:

We have shown work of a student to solve a division of fractions. We are asked to check student's work.

Let us check

Convert mixed fraction into improper fraction:

Convert division problem to multiplication problem by flipping the 2nd fraction:

Therefore, the student made two mistakes and option D is the correct choice.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
