Answer 1

$a)\frac{19}{36}-\frac{10}{36}o\frac{11}{16}-\frac{7}{16}$

$\frac{19-10}{36}o\frac{11-7}{16}$

$\frac{9}{36}o\frac{4}{16}$

$\frac{1}{4}=\frac{1}{4}$

$b)\frac{56-43}{20}o\frac{37-5}{31}$

$\frac{13}{20}o\frac{32}{31}$

$\frac{31*13}{620}o\frac{32*20}{620}$

$\frac{403}{620}<\frac{640}{620}$

$c)\frac{19+15}{17}o\frac{23-2}{9}$

$\frac{34}{17}o\frac{21}{9}$

$2o\frac{7}{3}$

$2<\frac{7}{3}=2,33$

$d)\frac{9+11}{25}o\frac{87-7}{100}$

$\frac{20}{25}o\frac{80}{100}$

$\frac{4}{5}o\frac{4}{5}$

$\frac{4}{5}=\frac{4}{5}$
