selesaikan perkalian pecahan 1. 3 3\4 x 3 3\8= 2. 2 4\5 x 4 1\4= 3. 6 4\8 x 2 3\4 = pakai lampiran atau foto

1.
[tex] = 3 \frac{3}{4} \times 3\frac{3}{8} \\ = \frac{15}{4} \times \frac{27}{8} \\ = \frac{405}{32} =12 \frac{21}{32} [/tex]
2.
[tex] = 2\frac{4}{5} \times 4 \frac{1}{4} \\ = \frac{14}{5} \times \frac{17}{4 } \\ = \frac{7}{5} \times \frac{17}{2} = \frac{119}{10} = 11 \frac{9}{10} [/tex]
3.
[tex] = 6 \frac{4}{8} \times 2 \frac{3}{4} \ \\ = \frac{52}{8} \times \frac{11}{4} \\ = \frac{26}{8} \times \frac{11}{2} \\ = \frac{13}{4} \times \frac{11}{2} \\ = \frac{143}{8} = 17\frac{7}{8} [/tex]
