Answer:
6.75 feet
Step-by-step explanation:
We have to convert 81 inches to feet.
We can use unity method to solve this problem.
12 inches = 1 feet (Note that 12 inches make a foot not 21)
Dividing both sides by 12, we get:
1 inch = [tex]\frac{1}{12}[/tex] feet
Multiplying both sides by 81, we get:
81 inches = [tex]\frac{81}{12}[/tex] feet
81 inches = [tex]\frac{27}{4}[/tex] feet
81 inches = 6.75 feet
