6.) Use cross products to determine which satio forme a proportion
9/4
To determine if 9/4 forms a proportion, we need to compare it to another fraction and see if their cross products are equal.
Let's use a comparison fraction of 6/8.
The cross products of 9/4 are: 9 * 8 = 72 and 4 * 6 = 24.
Since the cross products are not equal (72 ≠ 24), 9/4 does not form a proportion with 6/8.
