Operasi hitung campuran pecahan: A. 2 1\6 × 7 5\13 : 2\5 B. 14 5\14 + 6\18 -2\13 C. 3 7\20 + 4,5 × (4\25 - 120 persen) Pls di jawab bsok d kumpul

A.
[tex] = 2 \frac{1}{6} \times 7 \frac{5}{13} \div \frac{2}{5} \\ = \frac{13}{6} \times \frac{96}{13} \times \frac{5}{2} \\ = \frac{6240}{156} \\ = 40[/tex]
B.
[tex] = 14 \frac{5}{14} + \frac{6}{18} - \frac{2}{13} \\ = \frac{201}{14} + \frac{6}{18} - \frac{2}{13} \\ = \frac{47034 + 1902 - 504}{3276} \\ = \frac{48432}{3276} \\ = 14.78[/tex]
