which ratio is not equivalent to 48/64 ? a. 2/3 b. 6/8 c. 12/16 d. 45/60

hello there! The answer is A. 2/3

If you fully simplify 48/64, you get 3/4. Now, let's simplify the rest of the equations. If they are also 3/4, we know they are equivalent and not the answer.

A. 2/3 is already simplified as 2/3; & 2/3 ≠ 3/4 so this is NOT the correct answer

B. 6/8 simplified  = 3/4; this is NOT the answer

C. 12/16 simplified = 3/4; this is NOT the answer

D. 45/60 simplified = 3/4; this is NOT the answer

I hope this helps and have a great day! :)
