Jawaban:

1.

frac{5}{9} + frac{11}{27} = frac{3 times 5 + 11}{27} = frac{26}{27}

2.

frac{2}{3} + frac{5}{12} = frac{4 times 2 + 5}{12} = frac{13}{12} = 1frac{1}{12}

3.

frac{23}{24} + frac{1}{3} = frac{23 + 8 times 1}{24} = frac{31}{24} = 1frac{7}{24}

4.

frac{1}{3} times frac{6}{7} = frac{1 times 6}{3 times 7} = frac{6}{21} = frac{2}{7}

5.

1.75 + 0.57 = frac{232}{100} = frac{58}{25} = 2frac{8}{25} = 2.32

6.

6.35 - 4.13 = frac{222}{100} = frac{111}{50} = 2frac{11}{50} = 2.22

7.

frac{2}{5} times frac{2}{3} = frac{2 times 2}{5 times 3} = frac{4}{15}

8.

frac{4}{5} div frac{2}{5} = frac{4 times 5}{5 times 2} = frac{20}{10} = 2

9. Tulisan kurang jelas

10.

frac{1}{32} div frac{5}{6} = frac{1 times 6}{32 times 5} = frac{6}{160} = frac{3}{80}

11. Tulisan kurang jelas

Semoga membantu

Jawab:

1. frac{4}{9} + frac{11}{27} =

 frac{4*3}{9 * 3} = frac{12}{27}

 frac{12}{27} + frac{11}{27} = frac{23}{27}

2.  frac{2}{3} + frac{5}{12} =

    frac{2*4}{3 * 4} = frac{8}{12}

    frac{8}{12} + frac{5}{12} = frac{13}{12} = 1frac{1}{2}

3.  frac{23}{24} + frac{1}{3} =

    frac{1*8}{3 * 8} = frac{8}{24}

    frac{23}{24} + frac{8}{24} = frac{31}{24} = 1frac{7}{24}

4.  frac{1}{3} × frac{6}{7} = frac{6}{21} = frac{2}{7}

5. 1.75 + 0,57 = 2,32

6. 6,32 – 4,13 = 2,19

7.  frac{2}{5} × frac{2}{3} = frac{4}{15}

8. frac{4}{5} ÷ frac{2}{5} =

   frac{4}{5} × frac{5}{2} = frac{20}{10} = frac{2}{1}

9. frac{6}{8} + 15%

   75% + 15% = 100%

10. frac{1}{32} ÷ frac{5}{6} =

    frac{1}{32} × frac{6}{5} = frac{6}{160}

11. 15% + 4% = 19%
