Question

What is the result of converting 81 inches to feet? Remember, these are 21 inches in a foot.

Answer 1

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 = $\frac{1}{12}$ feet

Multiplying both sides by 81, we get:

81 inches = $\frac{81}{12}$ feet

81 inches = $\frac{27}{4}$ feet

81 inches = 6.75 feet
