trs bantu jawab yg 1 sampai 10 klo misalnya sanggup sampe nomor berapa gitu gapapa
Jawaban:
[tex]1) \frac{3}{5} \div 3 \frac{1}{3} \\ = \frac{3}{5} \div \frac{10}{3} \\ = \frac{3}{5} \times \frac{3}{10} \\ = \frac{9}{50} [/tex]
[tex]2) \frac{8}{9} \div 9 \frac{1}{3} \\ = \frac{8}{9} \div \frac{28}{3} \\ = \frac{8}{9} \times \frac{3}{28} \\ = \frac{24}{252} \\ = \frac{2}{21} [/tex]
[tex]3)2 \frac{1}{5} \div \frac{5}{8} \\ = \frac{11}{5} \times \frac{8}{5} \\ = \frac{88}{25} \\ = 3 \frac{13}{25} [/tex]
[tex]4)7,2 \div \frac{1}{8} \\ = \frac{72}{10} \times \frac{8}{1} \\ = \frac{576}{10} \\ = \frac{288}{5} \\ = 57 \frac{3}{5} [/tex]
[tex]5)4 \frac{3}{4} \div \frac{7}{11} \\ = \frac{19}{4} \times \frac{11}{7} \\ = \frac{209}{28} \\ = 7 \frac{13}{28} [/tex]
[tex]6) \frac{6}{7} \div 4 ,9 \\ = \frac{6}{7} \div \frac{49}{10} \\ = \frac{6}{7} \times \frac{10}{49} \\ = \frac{60}{343} [/tex]
[tex]7)8\% \div \frac{2}{9} \\ = \frac{8}{100} \times \frac{9}{2} \\ = \frac{72}{200} \\ = \frac{9}{25} [/tex]
[tex]8)0,3 \div \frac{4}{5} \\ = \frac{3}{10} \times \frac{5}{4} \\ = \frac{15}{40} \\ = \frac{3}{8} [/tex]
[tex]9) \frac{6}{5} \div 1,5 = \frac{6}{5} \div \frac{15}{10} \\ = \frac{6}{5} \times \frac{10}{15} \\ = \frac{60}{75} \\ = \frac{4}{5} [/tex]
[tex]10) \frac{4}{9} \div20\% \\ = \frac{4}{9} \div \frac{20}{100} \\ = \frac{4}{9} \times \frac{100}{20} \\ = \frac{400}{180} \\ = \frac{40}{18} \\ = \frac{20}{9} \\ = 2 \frac{2}{9} [/tex]
