Question

(3/8+-3/4+7/12):5/6+1/2

Answer 1

\(\left(\dfrac{3}{8}+\dfrac{-3}{4}+\dfrac{7}{12}\right):\dfrac{5}{6}+\dfrac{1}{2}\)

\(=\left(\dfrac{-3}{8}+\dfrac{7}{12}\right):\dfrac{5}{6}+\dfrac{1}{2}\)

\(=\dfrac{5}{24}:\dfrac{5}{6}+\dfrac{1}{2}\)

\(=\dfrac{1}{4}+\dfrac{1}{2}\)

\(=\dfrac{3}{4}\)

Answer 2

(3/8+-3/4+7/12):5/6+1/2

= (9/24+(-18)/24+14/24):5/6+1/2

= 5/24:5/6+1/2

=5/24.6/5+1/2

=1/4+1/2

=1/4+2/4

=3/4
