Answer:
38 7/18
Step-by-step explanation:
The LCD of denominators 3, 9 and 2 is 72; all three of these divide evenly into 72. Rewriting the original problem, we get
7 24/72 - 5 64/72 + 8 36/72
Rewriting the original quantities as improper fractions, we get
22/3 - 53/9 + 17/2
Applying the LCD, we get
24(22) 8(53) 17(36) 2764
----------- - ----------- + ---------- = ------------ = 38 7/18
72 72 72 72
[tex]7\frac{1}{3}-5\frac{8}{9}+8\frac{1}{2}= \frac{22}{3}-\frac{53}{9} +\frac{17}{2} = \frac{132}{18}-\frac{106}{18}+\frac{153}{18} =\frac{132-106+153}{18} =\frac{179}{18}=9\frac{17}{18}[/tex]
ok done. Thank to me :>
