[tex]14 \frac{1}{4}= \frac{14\cdot4+1}{4}= \frac{57}{4} [/tex]
[tex]10 \frac{3}{7}= \frac{10\cdot7+3}{3}= \frac{73}{7} [/tex]
[tex]\hbox {So, you have now } \frac{57}{4}-\frac{73}{7}=\frac{57\cdot7}{4\cdot7}-\frac{73\cdot4}{7\cdot4}= \frac{399}{28}-\frac{292}{28}=\boxed {\frac{107}{28} } [/tex][tex]=\boxed { 3\frac{23}{28} }[/tex]
