Answer 1

$( \frac{7}{20} - \frac{35}{8}) - ( - \frac {1}{30} - \frac{35}{8})$

$( - \frac{161}{40}) - ( - \frac{529}{120})$

$- \frac{161}{40} + \frac{529}{120}$

$\frac{23}{60}$

Answer 2

(7/20 - 4 3/8) - (-1/30 - 4 3/8) = (0.35 - 4.375) - (-4/120 - 4 45/120) = -4.025 - (-4 49/120) = -4 1/40 + 4 49/120 = -4 3/120 + 4 49/120 = 23/60
