Answer 3

I can help you with math problems. Here are the detailed solutions:

1) $48 - (-15) = 48 + 15 = 63$ 2) $25 - 32 = -7$ 3) $-5.5 - 2.8 = -8.3$ 4) $3.7 - 4.5 = -0.8$ 5) $-\frac{3}{4} - (-\frac{5}{6}) = -\frac{3}{4} + \frac{5}{6} = \frac{-9 + 10}{12} = \frac{1}{12}$ 6) $-3 - \frac{4}{9} = -\frac{27}{9} - \frac{4}{9} = -\frac{31}{9}$ 7) $3 \frac{5}{7} - 4 \frac{3}{8} = \frac{26}{7} - \frac{35}{8} = \frac{208 - 245}{56} = -\frac{37}{56}$ 8) $-\frac{7}{8} - (-\frac{9}{6}) = -\frac{7}{8} + \frac{9}{6} = \frac{-21 + 36}{24} = \frac{15}{24} = \frac{5}{8}$

I hope this helps. Do you have any other math questions?
