Answer 1

Bună! ✳

________

$a) \frac{11}{12}-^{2)} \frac{1}{6} =\frac{9}{12} ^{(3}=\frac{3}{4}$

$b) \frac{5}{36}-^{4)} \frac{1}{9} =\frac{1}{36}$

$c) \frac{19}{20} -^{4)} \frac{4}{5}= \frac{3}{20}$

$d)^{2)} \frac{5}{7}-\frac{3}{14} = \frac{7}{14}^{(7} =\frac{1}{2}$

$e) \frac{20}{63} -^{7)} \frac{2}{9} =\frac{6}{63} ^{(3} =\frac{2}{21}$

$f) \frac{11}{24} -^{2)} \frac{5}{12} =\frac{1}{24}$

$g) \frac{5}{18} -^{3)} \frac{1}{6} =\frac{2}{18} ^{(2} =\frac{1}{9}$

$h) ^{4)} \frac{1}{4} -\frac{3}{16} =\frac{1}{16}$
