Accepted Answer

$(6\frac{9}{14}-1\frac18)-(1-\frac57)=5\frac{31}{56}-\frac27=5\frac{15}{56}$.
$24-2\frac7{36}+\frac{11}{20}=21\frac{13}{180}$.
$(1\frac57-1)+(6\frac9{14}-\frac18)=\frac57+6\frac{65}{112}=7\frac{145}{784}$.
$(11\frac12-\frac4{15})-(7-\frac{19}{30})=4\frac{29}{30}-6\frac7{30}=4\frac{11}{15}$.
$(46\frac29-25)-(11\frac47-\frac23)=21\frac29-11\frac5{21}=9\frac{32}{63}$.
$(29-6\frac58)+(4-\frac57)=22\frac38+3\frac27=25\frac{37}{56}$.
$7\frac5{18}-3\frac2{27}+\frac{11}{54}=4+\frac{15-4+11}{54}=4\frac{11}{27}$.
$9\frac3{20}-2\frac3{25}+4=11+\frac{15-12}{100}=11\frac3{100}$.
$9\frac{11}{42}-(2\frac3{14}+1\frac1{21})=9\frac{11}{42}-3\frac{11}{42}=6$.
$5\frac{11}{12}-2\frac38-\frac7{48}=5\frac{44-18-7}{48}=5\frac{19}{48}$.
