Simplify 8/-3÷-4/9

a -8
b -6
c 6
d 8

The answer is 6 that means its c

(8/-3) / (-4/9) (P.S. 8/-3 = -8/3. The minus in the denominator can be moved to the numerator for a more proper form).
Dividing two fractions is equal to multiplying the first fraction by the inverse of the second fraction (The inverse of a fraction a/b is b/a). So the inverse of -4/9 = -9/4.
So (-8/3) / (-4/9) = (-8/3) * (-9*4) = (-8*-9)/3*4
-8*-9 = 72 (Multiplying 2 negative numbers give a positive answer)
3*4 = 12

(-8*-9)/3*4 = 72/12 = 6.

So (8/-3) ÷ (-4/9) = 6 (Answer C)

Hope this Helps! :) 

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
