Question

(4-2 1/2×3/5)÷3 1/3-1/3=?​

Answer 1

$(4 - 2 \frac{1}{2} \times \frac{3}{5} ) \div 3 \frac{1}{3} - \frac{1}{3} = (4 - \frac{5 \times 3}{2 \times 5} ) \div \frac{10}{3} - \frac{1}{3} = (4 - 1 \frac{1}{2} ) \div \frac{10}{3} - \frac{1}{3} = \frac{5}{2} \div \frac{10}{3} - \frac{1}{3} = \frac{5 \times 3}{2 \times 10} - \frac{1}{3} = \frac{3}{4} - \frac{1}{3} = \frac{9}{12} - \frac{4}{12} = \frac{5}{12}$
