Question

Answer 1

j: \(=\dfrac{-2}{5}-\dfrac{15}{5}=\dfrac{-17}{5}\)

k: \(=\dfrac{-21}{7}-\dfrac{5}{7}=\dfrac{-26}{7}\)

j: \(=\dfrac{-12}{6}+\dfrac{-5}{6}=\dfrac{-17}{6}\)

Answer 2

\(j,-\dfrac{2}{5}+\left(-3\right)=-\dfrac{6}{15}+\dfrac{-45}{15}=-\dfrac{39}{15}\)

\(k,-3+\dfrac{5}{-7}=-\dfrac{63}{21}+-\dfrac{15}{21}=-\dfrac{78}{21}=\dfrac{26}{7}\)

\(l,-2+\dfrac{-5}{6}=-\dfrac{12}{6}+\dfrac{-5}{6}=-\dfrac{17}{6}\)
