Question

Jorge is building a table out of boards that are 3.75 inches wide he wants the table to be at least 36 inches wide what is the least number of boards he can use

Answer 1

10

Explanation:

If a board is 3.75 inches wide and he wants the table to be at least 36 inches wide, then we need to use the rule of three:

If a 1 board ---------------------------> 3.75 inches wide

x ---------------------------> 36 inches wide

x = (36 inches wide * 1 board)/3.75

x= 9.6 boards.

Like we cannot buy 9.6 boards, then we conclude that the least number of boards he can use is 10.
