Question

Answer 1

a: \(=48+\dfrac{3}{8}-2-\dfrac{1}{4}-6-\dfrac{2}{8}\)

=40-1/8=319/8

b: \(=\dfrac{-1}{4}\left(13+\dfrac{9}{11}+6+\dfrac{2}{11}\right)=\dfrac{-1}{4}\cdot20=-5\)

c: \(=4+\dfrac{5}{58}-3-\dfrac{1}{2}+8+\dfrac{15}{29}-3-\dfrac{5}{58}+7+\dfrac{14}{29}\)

=13-1/2=12,5

d: \(=8+\dfrac{1}{3}+5+\dfrac{2}{3}+6=19+1=20\)
