Answer 1

1)

$10\frac{5}{8} -x=7\frac{3}{5} \\x=10\frac{5}{8} -7\frac{3}{5}\\x=10\frac{25}{40} -7\frac{24}{40} \\x= 3\frac{1}{40}$

2)

$(x-2\frac{7}{8} )+3\frac{5}{6} =4\frac{2}{3} \\x-2\frac{7}{8}=4\frac{2}{3}-3\frac{5}{6}\\x-2\frac{7}{8}=4\frac{4}{6}-3\frac{5}{6}\\x-2\frac{7}{8}=3\frac{10}{6} -3\frac{5}{6}\\x-2\frac{7}{8}=\frac{5}{6} \\x=2\frac{7}{8}+\frac{5}{6}\\x=2\frac{21}{24}+\frac{20}{24} \\x=2\frac{41}{24}\\ x=3\frac{17}{24}$
