Question

Ex.3 repede dau coronita!!!!

Answer 1

$\frac{7}{5} - \frac{3}{4<strong></strong>}= \frac{28-15}{20} = \frac{13}{20}$
$\frac{8}{7}- \frac{1}{14}= \frac{16-1}{14}= \frac{15}{14}=1 \frac{1}{14}$
$\frac{1}{12} - \frac{1}{24}= \frac{2-1}{24} = \frac{1}{24}$
$\frac{5}{9} - \frac{1}{18} = \frac{10-1}{18} = \frac{9}{18} = \frac{1}{2}$
$\frac{3}{16}- \frac{1}{48}= \frac{9-1}{48}= \frac{8}{48}= \frac{1}{6}$
$\frac{5}{3}- \frac{2}{6} = \frac{10-2}{6}= \frac{8}{6}= \frac{4}{3}=1 \frac{1}{3}$
$\frac{7}{360} - \frac{1}{540} = \frac{21-2}{1080} = \frac{19}{1080}$
$\frac{11}{4}- \frac{13}{5} = \frac{55-52}{20} = \frac{3}{20}$
$4 \frac{3}{4} -2 \frac{2}{3} = \frac{19}{4}- \frac{8}{3}= \frac{57-32}{12}= \frac{25}{12}=2 \frac{1}{12}$
$13 \frac{1}{4}-6 \frac{1}{2} = \frac{53}{4}- \frac{13}{2}= \frac{40}{4} =10$
