step by step to see if my answer your answer

Answers

$14 (1)/(4)= (14\cdot4+1)/(4)= (57)/(4)$

$10 (3)/(7)= (10\cdot7+3)/(3)= (73)/(7)$

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

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
