Answer 2

Answer:

a)3.9

b) $-2\frac{11}{12}$

Step-by-step explanation:

a) $7\frac{1}{2} + (-3\frac{3}{5} )$ =    $\frac{15}{2}$ + ($-\frac{18}{5}$ )           Taking 10 as LCM OF 5 And 2

                     =$\frac{75- 36}{10}$ = $\frac{39}{10}$ = 3.9

b)$-2\frac{3}{4} + (-\frac{5}{6} ) - (-\frac{2}{3} )$= $-\frac{11}{4} + (-\frac{5}{6} ) + (\frac{2}{3} )$     Taking LCM AS 12

                                 = $\frac{-33 -10+8}{12}$

                                 = $\frac{-43+8}{12}$

                                 = $\frac{-35}{12}$

                                 = $-2\frac{11}{12}$
