Question

Do these pairs of values (x and y) represent two quantities that are

Answer 1

Answer:

d

Step-by-step explanation:

3/5 is equal to .6. however it can be simplified from 6/10, 9/15, etc

but 4/6 cannot be simplified to 2/5

Answer 2

Answer: B) No, because not all of the pairs represent the same ratio

For each row, divide y over x

Row 1:  y/x = 5/3 = 1.67 approximately

Row 2: y/x = 7.4 = 1.75

Row 3: y/x = 10/6 = 1.67 approximately

Row 4: y/x = 15/9 = 1.67 approximately

We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.
