tentukanlah hasil perkalian dan pembagian dari ketua bilangan pecahan berikut a.3/8 × 2 1/5 b.5 1/2 × 7 2/3 c.6:6/9 d.3 2/3:2 1/3
![]()
Penjelasan dengan langkah-langkah:
[tex]a. \frac{3}{8} \times 2 \frac{1}{5} = \frac{3}{8} \times \frac{11}{5} = \frac{3 \times 11}{8 \times 5} = \frac{33}{40} \\ b.5 \frac{1}{2} \times 7 \frac{2}{3} = \frac{11}{2} \times \frac{23}{3} = \frac{11 \times 23}{2 \times 3} = \frac{253}{6} = 42 \frac{1}{6} \\ c.6 \div \frac{6}{9} = 6 \div \frac{2}{3} = \frac{18}{2} = \frac{9}{1} = 9 \\ d.3 \frac{2}{3 } \div 2 \frac{1}{3} = \frac{11}{3} \div \frac{7}{3} = \frac{11 \times 3}{3 \times 7} = \frac{33}{21} = \frac{11}{7} = 1 \frac{4}{7} [/tex]
