[tex] \frac{3}{5} \div 2 = \frac{3}{5} \times \frac{1}{2} = \frac{3}{10} \\ \frac{5}{9} \div 3 = \frac{5}{9} \times \frac{1}{3} = \frac{5}{27} \\ \frac{7}{9} \div 4 = \frac{7}{9} \times \frac{1}{4} = \frac{7}{36} \\ \frac{4}{11} \div 5 = \frac{4}{11} \times \frac{1}{5} = \frac{4}{55} [/tex]

a) 3/5 : 2 = 3/5 · 1/2 = 3/10

b) 5/9 : 3 = 5/9 · 1/3 = 5/27

c) 7/9 : 4 = 7/9 · 1/4 = 7/36

d) 4/11 : 5 = 4/11 · 1/5 = 4/55
