Explicație pas cu pas:

$3 \frac{3}{8} \div 1 \frac{1}{4} \div \frac{3}{5} = \\ = \frac{3 \times 8 + 3}{8} \div \frac{1 \times 4 + 1}{4} \div \frac{3}{5} \\ = \frac{24 + 3}{8} \div \frac{4 + 1}{4} \div \frac{3}{5 } \\ = \frac{27}{8} \div \frac{5}{4} \div \frac{3}{5} \\ \\ \\ \\ amplificam \: pe \: fiecare \: cu \: factorul \: comun \\ \\ \\ \frac{27 \times 5}{8 \times 5} \div \frac{5 \times 10}{4 \times 10} \div \frac{3 \times 8}{5 \times 8} \\ = \frac{135}{40} \div \frac{50}{40} \div \frac{24}{40}$
