Answer:


(56)/(72) and
(7)/(9) are indeed proportional

Explanation:

In order to confirm that
(7)/(9) is proportional to
(56)/(72), you need to make sure both fractions share the same denominator. In this case, it is better to multiply 9 by a value that causes the product to be 72 than to divide 72 by a number to get to 9. 72 is eight times greater than 9, so you multiply
(7)/(9) by
(8)/(8) (This is important as you need to make sure you aren't changing the value of the fraction when multiplying a number to it, so you must be sure to multiply your fraction by the number over itself - which is essentially one - to ensure that you are keeping the value of the fraction the same) and you will get
(7*8)/(9*8) =(56)/(72), this means the fractions
(7)/(9) and
(56)/(72) are proportional.
