Answer:

2 +  \frac{1}{3}  +  \frac{1}{ - 5}  \\  \\  = 2 +  \frac{1}{3}  -  \frac{1}{5}  \\  \\  =  \frac{6 + 1}{3}  -  \frac{1}{5}  \\  \\  =  \frac{35 - 3}{15 }  \\  \\  =  \frac{32}{15} (answer)

Question:-(2)

 - 3 +  \frac{2}{ - 3}  +  \frac{ - 3}{ - 5}

Answer:

 - 3 +  \frac{2}{ - 3}  +  \frac{ - 3}{ - 5}  \\  \\  =  - 3 -  \frac{2}{3}  +  \frac{3}{5}  \\  \\ =   \frac{ -45 - 10 + 9}{15}  \\  \\  =  \frac{ - 46}{15} (answer)

Question:-(3)

 \frac{ - 15}{169}  +  \frac{2}{13}  +  \frac{7}{26}

Answer:

 \frac{ - 15}{169}  +  \frac{2}{13}  +  \frac{7}{26}  \\  \\  = \frac{(2 \times ( - 15) + (26 \times 2) + (13 \times 7)}{338}   \\  \\  =  \frac{ - 30 + 52 + 91}{338}  \\  \\  =  \frac{113}{338} (answer)

Question:-(4)
