Answer 2

A. 49/81

B. -66/5

C. 9/8

Explanation:

Slide 1:

Dividing fractions is exactly the same as multiplying fractions, you just flip the second fraction so the expression becomes -7/9*7/-9 which is 49/81.

`(-7)/(9)*(7)/(-9) =(-49)/(-81) =(49)/(81)`

Slide 2:

To make 22 a fraction you just put it over 1 to make 22/1 and you just multiply across. -66/5

Slide 3:

To transform a mixed number into an improper fraction, you multiply the denominator by the whole number and then add the numerator. You take that number and put it over the denominator. You should now have -9/2. Multiply across. Cancel out the negatives. 9/8
