Answer 1

$1)\frac{ 35 }{ 11 } - \frac{ 14 }{ 11 } =$

$\frac{35-14}{11} =$

$\frac{21}{11}$

$2)\frac{ 35 }{ 24 } - \frac{ 17 }{ 24 } =$

$\frac{35-17}{24} =$

$\frac{18}{24} =$

$\frac{3}{4}$

$3)\frac{ 29 }{ 12 } - \frac{ 44 }{ 48 } =$

$\frac{29}{12}-\frac{11}{12} =$

$\frac{29-11}{12} =$

$\frac{18}{12} =$

$\frac{3}{2}$

$1)1 \frac { 5 } { 18 } - \frac{ 4 }{ 9 } =$

$\frac{18+5}{18}-\frac{4}{9} =$

$\frac{23}{18}-\frac{4}{9} =$

$\frac{23}{18}-\frac{8}{18} =$

$\frac{23-8}{18} =$

$\frac{15}{18} =$

$\frac{5}{6}$

$2)3 \frac { 5 } { 6 } - \frac{ 7 }{ 8 } =$

$\frac{18+5}{6}-\frac{7}{8} =$

$\frac{23}{6}-\frac{7}{8} =$

$\frac{92}{24}-\frac{21}{24} =$

$\frac{92-21}{24} =$

$\frac{71}{24}$

$3)2 \frac { 9 } { 10 } - 1 \frac { 3 } { 8 } =$

$\frac{20+9}{10}-\frac{1\times 8+3}{8} =$

$\frac{29}{10}-\frac{1\times 8+3}{8} =$

$\frac{29}{10}-\frac{8+3}{8} =$

$\frac{29}{10}-\frac{11}{8} =$

$\frac{116}{40}-\frac{55}{40} =$

$\frac{116-55}{40} =$

$\frac{61}{40}$
