Question

B=\(\dfrac{11}{17}+\left(-\dfrac{8}{19}\right)+\left(-\dfrac{3}{4}\right)+\dfrac{6}{17}-\dfrac{30}{19}\)

Answer 1

\(B=\dfrac{11}{17}+\left(-\dfrac{8}{19}\right)+\left(-\dfrac{3}{4}\right)+\dfrac{6}{17}-\dfrac{30}{19}\\ \Rightarrow B=\left(\dfrac{11}{17}+\dfrac{6}{17}\right)+\left(-\dfrac{8}{19}-\dfrac{30}{19}\right)-\dfrac{3}{4}\\ \Rightarrow B=1-2-\dfrac{3}{4}\\ \Rightarrow B=-\dfrac{7}{4}\)
