Pembahasan

  • No 1

\sf 3 \frac{1}{2} - \frac{4}{5}

\sf = \frac{7}{2} - \frac{4}{5}

\sf = \frac{ 35}{10} - \frac{8}{10}

\sf = \frac{27}{10}

\sf = 2 \frac{7}{10}

  • No 2

\sf \frac{3}{8} \times 24

\sf = \frac{3}{(8 \div 8)} \times (24 \div 8)

\sf = \frac{3}{1} \times 3

\sf = 9

  • No 3

\sf \frac{4}{9} + 5 \frac{2}{6}

\sf = \frac{4}{9} + \frac{32}{6}

\sf = \frac{8}{18} + \frac{96}{18}

\sf = \frac{104}{18}

\sf = 5 \frac{14}{18}

\sf = 5 \frac{7}{9}

  • No 4

\sf 1,47 - 0,122

\sf = 1,348

  • No 5

\sf 2 \frac{1}{4} \div \frac{6}{10}

\sf = \frac{9}{4} \div \frac{6}{10}

\sf = \frac{9}{4} \times \frac{10}{6}

\sf = \frac{(9 \div 3)}{(4 \div2)} \times \frac{(10 \div 2)}{(6 \div 3)}

\sf = \frac{3}{2} \times \frac{5}{2}

\sf = \frac{15}{4}

\sf = 3 \frac{3}{4}

  • No 6

\sf \frac{1}{2} \times \frac{3}{4} \div \frac{1}{5}

\sf = \frac{3}{8} \div \frac{1}{5}

\sf = \frac{3}{8} \times \frac{5}{1}

\sf = \frac{15}{8}

\sf = 1 \frac{7}{8}

  • No 7

\sf 7 \div \frac{1}{5}

\sf = \frac{7}{1} \times \frac{5}{1}

\sf = \frac{35}{1}

\sf = 35

  • No 8

\sf 45\% + 25\%

\sf = 70\%

  • No 9

\sf 1 \frac{1}{4} \times \frac{2}{3} \div 0,6

\sf = \frac{5}{4} \times \frac{2}{3} \div \frac{6}{10}

\sf = \frac{5}{(4 \div 2)} \times \frac{(2 \div 2)}{3} \div \frac{6}{10}

\sf = \frac{5}{2} \times \frac{1}{3} \div \frac{6}{10}

\sf = \frac{5}{6} \times \frac{10}{6}

\sf = \frac{5}{(6 \div 2)} \times \frac{(10 \div 2)}{6}

\sf = \frac{5}{3} \times \frac{5}{6}

\sf = \frac{25}{18}

\sf = 1\frac{7}{18}

  • No 10

\sf 4 \frac{2}{3} \div 1 \frac{1}{6} - 2\frac{1}{3}

\sf = \frac{14}{3} \div \frac{7}{6} - \frac{7}{3}

\sf = \frac{14}{3} \times \frac{6}{7} - \frac{7}{3}

\sf = \frac{(14 \div 7)}{(3 \div 3)} \times \frac{(6 \div 3)}{(7 \div 7)} - \frac{7}{3}

\sf = \frac{2}{1} \times \frac{2}{1} - \frac{7}{3}

\sf = \frac{4}{1} - \frac{7}{3}

\sf = \frac{12}{3} - \frac{7}{3}

\sf = \frac{5}{3}

\sf = 1 \frac{2}{3}
