Question

Convert 32 feet 6-1/4 inches (measured to the nearest 1/4 inch) to decimal feet. How many significant figures are there?

Answer 1

32.52 feet

Explanation:

We are given the following in the question:

`32\text{ feet }6(1)/(4)\text{ inches}`

We have to convert it into feet.

Thus, we convert the inch part in feet

1 feet = 12 inches

`6(1)/(4)\text{ inches}\\\\= 6.25\text{ inches}\\\\= (6.25)/(12)\text{ feet}\\\\= 0.52\text{ feet}`

Converting into feet:

`32 +0.52\text{ feet}\\=32.52\text{ feet}`

There are 4 significant figures.
