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.

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
