Vaughn Conley · Answer 1

4/7 is a proportion to 16/28 because when you multiply both sides by 4 (4/4) you get 16 16/28. C & D are incorrect because 4/7 does not equal 16/35 or 20/25. A. & C are correct because you multiply (B.) or divide (A.) the numerator and denominator by (4/4) to get the right side of the equation.

So A & B are YES. C & D are NO
