To find out if the fractions are proportional, we need to check if their cross-products are equal.Cross-product of 3/5 and 9/15:

3/5 × 9/15 = (3 × 9)/(5 × 15) = 27/75We can simplify 27/75 by dividing both the numerator and denominator by their greatest common factor, which is 3:

27/75 = (3 × 9)/(3 × 25) = 9/25Therefore, the cross-product of 3/5 and 9/15 is 9/25.Since the cross-products are not equal to each other, the fractions are not proportional.
