Answer 1

`\bf \stackrel{\textit{small cabinets}}{11.5}\qquad \qquad \stackrel{\textit{large cabinets 2.3 times as long}}{2.3(11.5)\implies 26.45} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{board's length in feet}}{10(1)/(2)\implies 10.5}\implies \stackrel{\textit{length in inches}}{10.5(12)\implies 126} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{\textit{how many times does 26.45 go into 126?}}{126/ 26.45 ~~\approx ~~4.76}~\hfill \boxed{\stackrel{\textit{whole cabinets only}}{4}}`

bearing in mind that, a foot = 12 inches.
