Answer:
Explanation:
We know that 1 yard is equal to 3 feet.
3 yards = 3 x 3 = 9 feet
So, 3 yards is equal to 9 feet. So, write the letter B in front of 3 yards.
We know that 1 yard is equal to 36 inches.
2 yards = 2 x 36 = 72 inches
So, 72 inches is equal to 2 yards. So, write the letter C in front of 72 inches.
We know that 1 feet is equal to 12 inches.
3 feet = 3 x 12 = 36 inches
So, 3 feet is equal to 36 inches. So, write the letter A in front of 3 feet.
