Verified Answer :

make them improper fractions:
14 1/4 would be 57/4
10 3/7 would be 73/7
Make them the same common denominator:
Times 57/4 by 7/7 =399/28
Times 73/7 by 4/4 =292/28
Now subtract them:
107/28 
Now Simplify:
107/28= (3*28+23)/28=3+23/28= 3 23/28
The Answer:
3 23/28

\(14 \frac{1}{4}= \frac{14\cdot4+1}{4}= \frac{57}{4}\)

\(10 \frac{3}{7}= \frac{10\cdot7+3}{3}= \frac{73}{7}\)

\(\hbox {So, you have now } \frac{57}{4}-\frac{73}{7}=\frac{57\cdot7}{4\cdot7}-\frac{73\cdot4}{7\cdot4}= \frac{399}{28}-\frac{292}{28}=\boxed {\frac{107}{28} }\)\(=\boxed { 3\frac{23}{28} }\)
