Răspuns:

a) $1\frac{17}{18}:5\frac{1}{4} =\frac{18+17}{18}:\frac{5*4+1}{4} =\frac{35}{18}:\frac{21}{4}= \frac{35}{18}*\frac{4}{21}= \frac{5*2}{9*3}= \frac{10}{27}$

b) $1\frac{13}{27} :1\frac{7}{18} =\frac{27+13}{27}:\frac{18+7}{18} =\frac{40}{27}:\frac{25}{18}= \frac{40}{27}*\frac{18}{25}=\frac{8*2}{3*5}=\frac{16}{15}$
