Question

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

Answer 1

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

\(\frac{3}{2}x\frac{7}{2}+\frac{-11}{15}:\frac{11}{30}\)

\(\frac{3}{2}x\frac{7}{2}+-2\)

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

13/4

Answer 2

3/2 . 7/2 + (-5/6 +1/10 ):11/30

= 21/4 + (-11/15) : 11/30

= 21/4 + (-2) 

= 13/4
