Question

Mr. Martin is ordering new tables for his classroom, which he wants to place them side by side in a long row across the room. The room is 23 2/3 feet wide and the tables are each 6.5 feet long. How many tables can Mr. Martin fit across the width of his classroom?________

Answer 1

What we are going to do is first to convert the mixed number to a fraction and then convert 6.5 into a fraction too, then we will divide the wide of the room by the length of each table, to know how many tables fits in the classroom:

`23(2)/(3)=(23(3)+2)/(3)=(71)/(3)`

and

`6.5=(2(6.5))/(2)=(13)/(2)`

then

`((71)/(3))/((13)/(2))=((71)(2))/((3)(13))=(142)/(39)=3.641025641`

Since Mr. Martin can't cut the tables, we need to aproximate the number to 3

then the answer is that Mr. Martin can fit 3 tables across the width of the classroom.
