Question

calculati: (1/3+0,75)×(2+3/4)÷[2/3÷(0,8+0,8×1/3)]​

Answer 1

$( \frac{1}{3} + 0 .75) \times (2 + \frac{3}{4}) \div ( \frac{2}{3} \div (0.8 \times \frac{1}{3} ))$

$( \frac{1}{3} + \frac{3}{4}) \times \frac{11}{4} \div ( \frac{2}{3} \div ( \frac{4}{5} \times \frac{4}{5} \times \frac{1}{3} ))$

$\frac{13}{12} \times \frac{11}{4} \div ( \frac{2}{3} \div ( \frac{4}{5} + \frac{4}{15} ))$

$\frac{13}{12} \times \frac{11}{4} \div ( \frac{2}{3} \div \frac{16}{15} )$

$\frac{13}{12} \times \frac{11}{4} \times ( \frac{2}{3} \times \frac{15}{16})$

$\frac{13}{12} \times \frac{11}{4} \div \frac{5}{8}$

$\frac{13}{12} \times \frac{11}{4} \div \frac{5}{8}$

$\frac{13}{12 } \times 11 \times \frac{2}{5}$

$\frac{13}{6} \times 11 \times \frac{1}{5}$

$\frac{143}{30}$
