Aman is building a gazebo and plans to use for the floor two boards that are 8 and three fourths feet , four boards that are 13 and five eighths feet , and two boards that are 6 one half feet. find the total number of feet in all the boards.

The total number of feet in all the boards is 90 and 5/6 feet

Step-by-step explanation:

First, it is necessary to transform the mixed number into a fraction. This can be made following the next rule:

So, the number 8 and three fourth feet is equal to:

That means that we two boards that are 35/3 feet. So, multiplying 2 by 35/3 we get the total feets for the first type of board. That is:

At the same way, we can calculate the total number of feet for the second and third type of board as:

Finally, to find the total number of feet in all the boards, we need to sum the total number of feet for every type as:

Converting this number to a mixed number we get:

Because, when we divide 545 by 6, we get 90 as a quotient, 5 is the remainder and 6 is the divisor.
