Answer:
Step-by-step explanation:
1) e) -3 - (-1) = -3 + (+1) = -2
f) [tex]3\frac{7}{8}- (-1\frac{1}{4}) = \frac{31}{8}-(-\frac{5}{4})\\[/tex]
[tex]= \frac{31}{8} + (+\frac{5}{4})\\\\= \frac{31}{8} + \frac{5*2}{4*2}\\\\= \frac{31}{8} + \frac{10}{8}\\\\= \frac{31+10}{8}\\\\= \frac{41}{8}\\\\= 5\frac{1}{8}[/tex]
