Which of the following option one or option? Two is a proportion? Option 1 5/6=15/18 option 2 5/6=20/18

Option one is a proportion.

To determine if two ratios form a proportion, you need to check if the cross products are equal.

In option one:

5/6 = 15/18

To find the cross products, you multiply the numerator of the first ratio (5) by the denominator of the second ratio (18), and multiply the numerator of the second ratio (15) by the denominator of the first ratio (6).

The cross products would be:

5 * 18 = 90
15 * 6 = 90

Since the cross products are equal (both equal to 90), option one is a proportion.

In option two:

5/6 = 20/18

To find the cross products, you multiply the numerator of the first ratio (5) by the denominator of the second ratio (18), and multiply the numerator of the second ratio (20) by the denominator of the first ratio (6).

The cross products would be:

5 * 18 = 90
20 * 6 = 120

Since the cross products are not equal (90 is not equal to 120), option two is not a proportion.
