Are the ratios 4:6 and 6:18 equivalent?
yes or no

No they are not equal because 4:6 is 2:3 (simplified form)

And 6:18 is 1:3 (simplified form)

No, they are not.

Step-by-step explanation:

6:18 cannot be simplified down to 4:6. 4×1.5=6, but 6×1.5 does not equal 18. 6×3=18, but as ratios work, what we do to one side, we do to the other, 4×3 does not equal 6. Therefore the ratios are not equivalent to each other. Hope this helped. 4:6 has a simplified and equivalent form which is 2:3, and for 6:18, 2:9. The two ratios simplified do not equal to each other as well. This proves my answer even more.

the answer

b. they are parallel and will never intersect.
