Question

Is the ratio 25 to 16 proportional to 5 to 4.

Answer 1

no

Explanation:

because if you divide 25 by 16 you get 1.5625 and if you divide 5 by 4 you 1.25, so they are not proportional. and another way to see if its proportional or not, is to divide the numerators by the same number as you did with the denominators. for example, 25/5 = 5 but 16/5 does not equal 4, so they aren't proportional.

Answer 2

No because 5:4 time 4 you get 20:16 not 25:16 and if you manage 25 it will be 25:20 so not promotional
