Well if you look at 81, the factors of 81 are 1,3,9,27, and 81. And the factors of 64 are 1,2,4,8,16,32, and 64. They do not have a single common factor. So the GCF for 81 and 64 would be 1.

Which of the following measurements are less than 5 feet? Select all that apply. A. 56 inches B. 1 yard C. 1 yard 2 feet D.
Gennadij [26K]

Answer:

A and B

Step-by-step explanation:

Let's convert 5 feet into inches and yards. We will use the conversions:

1 ft = 12 in

1 yd = 3 ft

So, 5 feet = 5 * 12 = 60 inches. Looking at the answer choices, A says 56 inches, which is less than 60, so that can work.

5 feet = 3 feet + 2 feet = 1 yd + 2 ft. Looking at the answer choices, B works because it says 1 yd, which is clearly less than 1 yd + 2 ft. However, C doesn't work because 1 yd 2 ft is equal to 5 ft.

Thus, the answers are A and B. (Note that as you didn't provide choice D, I will assume it is not an answer)

Hope this helps!
