You have a piece of wood that is 7 3/4 feet long.  You want to cut one piece that is 3 7/12 feet long and one piece that is 4 1/12 feet long.  Do  you have enough wood? Explain.

[tex]3\frac7{12}+4\frac1{12}=7\frac8{12}\\ \\ 7\frac34=7\frac9{12}\\\\ 7\frac8{12}<7\frac9{12}\\\\ Answer:I\ have\ enough\ wood.[/tex]
[tex]7 \frac{3}{4} - (3 \frac{7}{12} + 4 \frac{1}{12} ) = 7 \frac{3}{4} - 7 \frac{8}{12} = 7 \frac{9}{12} - 7 \frac{8}{12} = \frac{1}{12} [/tex]

yeah , enough ...
