Given:
5/8 = 15/18 to check if their proportional
Solution:
We can check if their proportional by checking if their cross-products are similar.
[tex] \sf \: \frac{5}{8} = \frac{15}{18} [/tex]
➟ 5 • 18 = 90
➟ 8 • 15 = 120
Therefore, after analysing the value we noticed they aren't similar which means they are not proportional.
