Question

a builder is building a fence with 6 and 1/4 inch wide wooden boards arranged side-by-side with no gaps. How many borders are needed to build a fence that is 150 in Long​

Answer 1

Number of boards required is 24

Explanation:

A builder is building a fence with 6 and 1/4 inch wide wooden boards arranged side-by-side with no gaps.

`\texttt{Length of 1 board = }6(1)/(4)in\\\\\texttt{Length of 1 board = }(6* 4+1)/(4)=(25)/(4)in`

We need to build a fence that is 150 in long​.

Length of fence = Number of boards required x Length of 1 board

`150=\texttt{Number of boards required }* (25)/(4)\\\\\texttt{Number of boards required }=(150* 4)/(25)\\\\\texttt{Number of boards required }=6* 4=24`

Number of boards required = 24
