б) (1 1/2 - 1/4) / (3 3/4) + 2/3 6)

В) 4 5/6 - 5/8 - 2 1/4 * 1/6

г) (4 - 2 1/2 * 3/5) / (3 1/3) - 1/3​

Answer 1

• а)
• $3\frac{2}{15} + 1\frac{2}{5} \div \frac{1}{3} - 2 \frac{1}{5} = 5\frac{2}{15}$
• б)
• $(1 \frac{1}{2} - \frac{1}{4} ) \div (3 \frac{3}{4} + 2 \frac{3}{6} ) = \frac{1}{5}$
• в)
• $4 \frac{5}{6} - \frac{5}{8} - 2 \frac{1}{4} \times \frac{1}{6} = 3 \frac{5}{6}$
• г)
• $(4 - 2 \frac{1}{2} \times \frac{3}{5} ) \div (3 \frac{1}{3} - \frac{1}{3} ) = \frac{5}{6}$
