mohon pakai cara yah kak
[tex]a. \: \: 5 \div \frac{2}{11} = \frac{5}{1} \times \frac{11}{2} = \frac{55}{2} = 27 \frac{1}{2} [/tex]
[tex]b. \: \: 36\frac{1}{4} \div 8 \frac{3}{4} = \frac{145}{4} \div \frac{35}{4} = \frac{145}{4} \times \frac{4}{35} = \frac{145}{1} \times \frac{1}{35} = \frac{145}{35} = \frac{29}{7} = 4 \frac{1}{7} \\ [/tex]
[tex]c. \: \: (5 \frac{1}{4} \times \frac{16}{7} ) \div \frac{2}{3} = ( \frac{21}{4} \times \frac{16}{7} ) \div \frac{2}{3} = ( \frac{3}{1} \times \frac{4}{1} ) \div \frac{2}{3} = \frac{12}{1} \times \frac{3}{2} = \frac{6}{1} \times \frac{3}{1} = 18 \\ [/tex]
[tex]d. \: \: (18 \frac{2}{9} \div 9 \frac{1}{9} ) \div 1 \frac{1}{3} = ( \frac{164}{9} \div \frac{82}{9} ) \div \frac{4}{3} = ( \frac{164}{9} \times \frac{9}{82} ) \div \frac{4}{3} = ( \frac{2}{1} \times \frac{1}{1} ) \div \frac{4}{3} = \frac{2}{1} \times \frac{3}{4} = \frac{1}{1} \times \frac{3}{2} = \frac{3}{2} = 1 \frac{1}{2} \\ [/tex]
[tex]e. \: \: ( \frac{2}{7} \div \frac{40}{21} ) \times ( \frac{3}{10} \div \frac{9}{20} ) = ( \frac{2}{7} \times \frac{21}{40} ) \times ( \frac{3}{10} \times \frac{20}{9} ) = \frac{3}{20} \times \frac{2}{3} = \frac{2}{20} = \frac{1}{10} \\ [/tex]
[tex]f. \: \: ( \frac{7}{9} - \frac{5}{27} ) \times ( \frac{1}{3} - \frac{5}{18} ) = ( \frac{21 - 5}{27} ) \times ( \frac{6 - 5}{18} ) = \frac{16}{27} \times \frac{1}{18} = \frac{8}{27} \times \frac{1}{9} = \frac{8}{ 243} \\ [/tex]
