Which option equals 79 1/2 inches?

78 5/8" 79 1/2" 80 3/8" 81 3/4"

Correct Answer:

79 1/2"

Explanation:

Reading and comparing mixed numbers in inches means adding the whole inches to the fractional part. Convert each to a common form to see which matches 79 1/2. 78 5/8 equals 78 + 5/8 = 78.625 inches. 79 1/2 equals 79 + 1/2 = 79.5 inches. 80 3/8 equals 80 + 3/8 = 80.375 inches. 81 3/4 equals 81 + 3/4 = 81.75 inches. 79 1/2 inches is exactly 79.5, so that option matches the target. If you prefer fractions, 79 1/2 is 79 4/8, while the others are 78 5/8, 80 3/8, and 81 6/8—different values.
