Which of the following, Option 1 or Option 2, is a proportion?

Option 1: 7/8=20/22

Option 2: 7/8=21/24

Option _ is a proportion.

Option 1: 7/8=20/22

To determine which option is a proportion, we need to check if the two fractions are equal.

Let's simplify the fractions in both options to see if they are equivalent.

Option 1:

7/8 = 20/22

To simplify 20/22, we can divide both numerator and denominator by their greatest common divisor, which is 2.

20 ÷ 2 = 10
22 ÷ 2 = 11

So, option 1 becomes:

7/8 = 10/11

Option 2:

7/8 = 21/24

To simplify 21/24, we can also divide both numerator and denominator by their greatest common divisor, which is 3.

21 ÷ 3 = 7
24 ÷ 3 = 8

So, option 2 becomes:

7/8 = 7/8

Now, by comparing both options, we see that option 2 is a proportion because the two fractions are identical (both are 7/8).

Therefore, the answer is Option 2.
