Question

3/2.7/2+(-5/6+1/10):11/30)

Answer 1

\(\dfrac{3}{2}.\dfrac{7}{2}+\left(\dfrac{-5}{6}+\dfrac{1}{10}\right):\dfrac{11}{30}\)

=\(\dfrac{21}{4}\)+(\(\dfrac{-25}{30}+\dfrac{3}{30}\)):\(\dfrac{11}{30}\)

=\(\dfrac{21}{4}\)+\(\dfrac{-11}{15}\):\(\dfrac{11}{30}\)

=\(\dfrac{21}{4}\)+(-2)

=\(\dfrac{21}{4}\)+\(\dfrac{-8}{4}\)=\(\dfrac{13}{4}\)

Answer 2

\(\dfrac{3}{2}.\dfrac{7}{2}+\left(\dfrac{-5}{6}+\dfrac{1}{10}\right):\dfrac{11}{30}\)

\(=\dfrac{21}{4}+\dfrac{-11}{15}:\dfrac{11}{30}\)

\(=\dfrac{21}{4}+\left(-2\right)\)

\(=\dfrac{13}{4}\)
