Answer 1

a) $\frac{3}{4} :\frac{2}{5}$

Conform formulei: $\frac{a}{b} :\frac{c}{d} =\frac{a}{b} *\frac{d}{c}$, vom avea: $\frac{3}{4} *\frac{5}{2} =\frac{3*5}{4*2} =\frac{15}{8}$

b) $(-\frac{1}{2}):\frac{3}{7} =(-\frac{1}{2} )*\frac{7}{3} =-\frac{7}{6}$

c) $\frac{2}{3} :(-\frac{3}{5})=\frac{2}{3} *(-\frac{5}{3} )=-\frac{10}{9}$
