Question

Answer 1

e: \(=\left(\dfrac{3}{5}+\dfrac{3}{7}-\dfrac{1}{35}\right)+\left(\dfrac{3}{11}-\dfrac{3}{4}-\dfrac{23}{44}\right)+\dfrac{-2}{97}\)

\(=\dfrac{21+15-1}{35}+\dfrac{12-33-23}{44}+\dfrac{-2}{97}\)

\(=1-1+\dfrac{-2}{97}=\dfrac{-2}{97}\)

f: \(=-15.5\cdot30+3.5\cdot30=-12\cdot30=-360\)
