Answer #1

well what you do is set them as a fraction first…so 1:2 would be 1/2. then when you have two fractions, you set them next to each other (ex. 1/2 = 3/4) and then you multiply the two times the three and see what that is ( so it would be 6) and then you multiply the one by the four and see what that is (4) and since 6 doesn’t equal 4, the fraction isn’t proportional. but if they DO equal each other, the fraction is proportional.

If that doesn’t make sense let me know and I can clarify it a little.
