Penjelasan dengan langkah-langkah:
a.
[tex] \frac{6}{12} \times \frac{8}{9} = \frac{2}{3} \times \frac{2}{3} = \frac{2 \times 2}{3 \times 3} = \frac{4}{9} [/tex]
[tex] \frac{2}{3} + \frac{4}{9} = \frac{6 + 4}{9} = \frac{10}{9} [/tex]
b.
[tex] \frac{3}{5} \div \frac{6}{10}= \frac{5}{3} \times \frac{6}{10} = \frac{5 \times 6}{3 \times 10} = \frac{30}{30} = 1[/tex]
[tex]1 + \frac{1}{2} = 1 \frac{1}{2} [/tex]
c.
[tex] \frac{1}{2} \div \frac{5}{6} \times \frac{5}{4} = \frac{1}{2} \times \frac{6}{5} \times \frac{5}{4} \\ = \frac{1}{1} \times \frac{3}{5} \times \frac{5}{4} = \frac{1 \times 3 \times 5}{1 \times 5 \times 4} = \frac{15}{20} = \frac{3}{4} [/tex]
d.
½ -¾×⅔+⅓
[tex] \frac{1}{2} - \frac{3}{4} = \frac{2 - 3}{4} = - \frac{1}{4} [/tex]
[tex] \frac{2}{3} + \frac{1}{3} = \frac{2 + 1}{3} = \frac{3}{3} = 1[/tex]
[tex]1 \times - \frac{1}{4} = \frac{4 - 1}{4} = \frac{3}{4} [/tex]
maaf jika salah, semoga membantu
