Second from the top

The answer you have selected:

40:8 , 50:10, 60:14, 90:18

Proportions can be viewed as fractions:

40/8, 50/10, 60/14, 90/18

Now we have to simplify these fractions

5 , 5 , 4.3, 5

Unfortunately, they do not all come out to the same number, so this answer is incorrect

The second answer from the top:

4/2 , 7/3.5, 8/4, 10/5

These all equal 2 when simplified

2, 2, 2, 2

This shows a proportional relationship between x and y. If you would like to continue to make sure the bottom two are incorrect, you can use the steps that I have used for the first two. Hope this helps :)

the correct answer is 5
