Question

-11/15.20/23+-11/15.3/23+-34/15

Answer 1

-11/15.20/23+-11/15.3/23+-34/15

\(=\frac{-11}{15}\left(\frac{20}{23}+\frac{3}{23}\right)+\frac{-34}{15}\)

\(=\frac{-11}{15}.1+\frac{-34}{15}\)

\(=\frac{-45}{15}=-3\)

Answer 2

\(\frac{-11}{15}.\frac{20}{23}+\frac{-11}{15}.\frac{3}{23}+\frac{-34}{15}\)

\(=\frac{-11}{15}.\left(\frac{20}{23}+\frac{3}{23}\right)+\frac{-34}{15}\)

\(=\frac{-11}{15}.1+\frac{-34}{15}\)

\(=\frac{-11+\left(-34\right)}{15}\)

\(=\frac{-45}{15}\)

\(=-3\)
