[tex]h)\frac{2}{9}:\frac{8}{3}=\frac{2}{9}*\frac{3}{8}=\frac{1*1}{3*4}=\frac{1}{12}[/tex]

[tex]i)\frac{10}{3}:\frac{4}{3}=\frac{10}{3}*\frac{3}{4}=\frac{5}{2}=2\frac{1}{2}[/tex]

[tex]j)\frac{36}{5}:\frac{6}{5}=\frac{36}{5}*\frac{5}{6}=\frac{36}{6}=6[/tex]

[tex]k)\frac{11}{4}:\frac{22}{5}=\frac{11}{4}*\frac{5}{22}=\frac{5}{8}[/tex]

[tex]l)\frac{17}{12}:\frac{17}{10}=\frac{17}{12}*\frac{10}{17}=\frac{5}{6}[/tex]

Szczegółowe wyjaśnienie:

g)7/8÷1 5/16=7/8×5/21=1/8×5/3=5/24

h)2/9÷2 2/3=2/9×3/8=1/3×1/4=1/12

i)3 1/3÷1 1/3=10/3÷4/3=10/3×3/4=5/1×1/2=5/2=2 1/2

j)7 1/5÷1 1/5=36/5÷6/5=36/5×5/6=6/1=6

k)2 3/4÷4 2/5=11/4÷22/5=11/4×5/22=1/4×5/2=5/8

l)1 5/12÷1 7/10=17/12÷17/10=17/12×10/17=1/6×5/1=5/6
