[tex]3 \times \frac{3}{8} \div 1 \times \frac{1}{4} \div \frac{3}{5} = \frac{27}{8} \div \frac{5}{4} \div \frac{3}{5} = \frac{27}{8} \times \frac{4}{5} \times \frac{5}{3} = \frac{27 \times 4 \times 5}{8 \times 5 \times 3} = \frac{27 \times 4}{8 \times 3} = \frac{27}{2 \times 3} = \frac{9}{2} = 4\times \frac{1}{2} [/tex]
