d/5/16-5/24

e/-24/17-[-7/17-1/16]

f/-11/6+2/5+-1/6

Answer 1

[Nguyễn Lê Phước Thịnh]

d: \(\dfrac{5}{16}-\dfrac{5}{24}=\dfrac{5\cdot3}{48}-\dfrac{5\cdot2}{48}=\dfrac{5}{48}\)

e: \(-\dfrac{24}{17}-\left(-\dfrac{7}{17}-\dfrac{1}{16}\right)\)

\(=-\dfrac{24}{17}+\dfrac{7}{17}+\dfrac{1}{16}=-1+\dfrac{1}{16}\)

\(=-\dfrac{15}{16}\)

f: \(\dfrac{-11}{6}+\dfrac{2}{5}+\dfrac{-1}{6}\)

\(=\left(-\dfrac{11}{6}-\dfrac{1}{6}\right)+\dfrac{2}{5}\)

\(=-2+\dfrac{2}{5}=\dfrac{-8}{5}\)
