The total number of all the boards in feet is equal to 80.
<h3>What is a fraction?</h3>
A fraction can be defined as a numerical quantity which isn't expressed as a whole number. Thus, a fraction is simply a part of a whole number.
<h3>How to calculate the total number of all the boards?</h3>
In order to determine the total number of all the boards in feet, we would have to add up all the board lengths as follows:
Total number = 10 3/4 + 10 3/4 + 12 5/8 + 12 5/8 + 12 5/8 + 12 5/8 + 6 1/2 + 6 1/2.
Sum of whole numbers = 10 + 10 + 12 + 12 + 12 + 12 + 6 + 6 = 80.
Sum of fractions = 3/4 + 3/4 + 5/8 + 5/8 + 5/8 + 5/8 + 1/2 + 1/2 = 5.
Total number = Sum of whole numbers + Sum of fractions
Total number = 80 + 5
Total number = 85 feet.
