Answer:
The two ratios given: 25/15 and 65/56 do not form a proportion.
Step-by-step explanation:
A proportion is formed when two ratios (or fractions) are equal. When you set the two ratios equal to each other:

You can then determine if they are equal by a few different methods. (1) You can cross-multiply the numbers and see if they are equal:
25 x 56 = 16 x 65 or 1040 ≠ 1400
You can also see if the numerators and denominators can be divided to form a common factor:
65 ÷ 25 = 2.6 and 56 ÷ 16 = 3.5
Since neither the products of cross-multiplication or the factors by division are equal, these two ratios do not form a proportion.
