Arnold has a picture frame with a width of 8 inches and a height of 6 inches. Which proportion could be used to calculate the dimensions of a smaller frame with a width of 5 inches, that is similar to the larger one?

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

it would open into a square depending on the type of envelope i’m not sure about the second part

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
