Answer 1

$7 \frac{17}{30} - (4 \frac{3}{4} - 1 \frac{5}{6} ) = \\ \\ = 7 \frac{17}{30} - (4 \frac{18}{24} - 1 \frac{20}{24} ) = \\ \\ = 7\frac{17}{30} - (3 \frac{42}{24} - 1 \frac{20}{24} ) = \\ \\ = 7 \frac{17}{30} - 2 \frac{22}{24} = \\ \\ = 7 \frac{17}{30} - 2 \frac{11}{12} = \\ \\ = 7 \frac{34}{60} - 2 \frac{55}{60} = \\ \\ = 6 \frac{94}{60} - 2 \frac{55}{60} = \\ \\ = 4\frac{39}{60} = 4 \frac{13}{20} = 4.65$
