Nine

#"1 foot"##=##"12 inches"#

Determine the number of inches in a #"7 ft"# long board.

#7"ft"xx("12 in")/(1"ft")="84 in"#

Divide the length of each board in inches by #"27 in"#.

#(84"in")/(27"in")=3.1#

So three #"27-in"# boards can be cut from #1# board that is #"7 ft"# long. The #.1# does not count.

So nine #"27-in"# boards can be cut from #3# boards that are #"7ft"# in length.
