Answer 2

\frac{1}{2} - \frac{1}{4} =\frac{2}{4} - \frac{1}{4} =\frac{1}{4}

 

\frac{5}{6} - \frac{2}{3} =\frac{5}{6} - \frac{4}{6} =\frac{1}{6}

 

\frac{3}{4} - \frac{3}{8} =\frac{6}{8} - \frac{3}{8} =\frac{3}{8}

 

3 \frac{5}{9} - \frac{1}{6} =\frac{32}{9} - \frac{1}{6} =\frac{96}{18} - \frac{3}{18} =\frac{93}{18} =\frac{31}{6}= 5 \frac{1}{6}

 

2 {1}{4} - 1 \frac{5}{6}= \frac{9}{4} - \frac{11}{6}= \frac{27}{12} - \frac{22}{12}= \frac{5}{12}

 

1 \frac{3}{4} - \frac{5}{6}= \frac{7}{4} - \frac{5}{6}= \frac{21}{12} - \frac{10}{12}= \frac{11}{12}

 

\frac{7}{8} - \frac{1}{4} - \frac{1}{2}= \frac{7}{8} - \frac{2}{8} - \frac{4}{8}= \frac{1}{8}

 

2 \frac{3}{7} - \frac{3}[4} - 1 \frac{1}{2}= \frac{17}{7} - \frac{3}{4} - \frac{3}{2}= \frac{68}{28} - \frac{21}{28} - \frac{42}{28}= \frac{5}{28}

 

2 \frac{5}{6} - \frac{7}{8} - 1 {1}{4}= \frac{17}{6} - \frac{7}{8} - \frac{5}{4}= \frac{68}{24} - \frac{21}{24} - \frac{30}{24}= \frac{17}{24}

 

3 \frac{11}{12} - \frac{5}{9} - 1 \frac{3}{4}= \frac{47}{12} - \frac{5}{9} - \frac{7}{4} = \frac{141}{36} - \frac{20}{36} - \frac{63}{36}= \frac{58}{36}= \frac{29}{18}= 1 \frac{11}{18}

 

10 - 3 \frac{1}{4} - 1 \frac{3}{5}= \frac{10}{1} - \frac{13}{4} - \frac{8}{5}= \frac{200}{20} - \frac{65}{20} - \frac{32}{20}= \frac{200}{20} - \frac{97}{20}= \frac{103}{20}= 5 \frac{3}{20}

 

7 - 2 \frac{1}{2} - 1 \frac{4}{5}= \frac{7}{1} - \frac{5}{2} - \frac{9}{5}= \frac{70}{10} - \frac{25}{10} - \frac{18}{10}= \frac{70}{10} - \frac{43}{10}= \frac{27}{10}= 2 \frac{7}{10}

 

2 \frac{7}{9} - 1 \frac{1}{6}= \frac{25}{9} - \frac{7}{6}= \frac{50}{18} - \frac{21}{18}= \frac{29}{18}= 1 \frac{11}{18}

 

3 \frac{14}{15} - 1 \frac{11}{30}= \frac{5}{15} - \frac{41}{30}= \frac{118}{30} - \frac{41}{30}= \frac{77}{30}= 2 \frac{17}{30}

 

2 \frac{7}{30} - 1 \frac{17}{20}= \frac{67}{30} - \frac{37}{20}= \frac{134}{60} - \frac{111}{60}= \frac{24}{60}= \frac{2}{5}

 

4 \frac{1}{100} - 2 \frac{3}{50}= \frac{401}{100} - \frac{103}{50}= \frac{401}{100} - \frac{206}{100}= \frac{195}{100}= 1 \frac{95}{100}=  1 \frac{19}{20}
