\(\dfrac{2}{3}-\dfrac{5}{3}:\dfrac{3}{4}+25\)\(\text{%}\)
\(=\dfrac{2}{3}-\dfrac{5}{3}:\dfrac{3}{4}+\dfrac{1}{4}\)
\(=\dfrac{2}{3}-\dfrac{5}{3}.\dfrac{4}{3}+\dfrac{1}{4}\)
\(=\dfrac{2}{3}-\dfrac{20}{9}+\dfrac{1}{4}\)
\(=\dfrac{6}{9}-\dfrac{20}{9}+\dfrac{1}{4}\)
\(=\dfrac{-14}{9}+\dfrac{1}{4}\)
\(=\dfrac{-56}{36}+\dfrac{9}{36}\)
\(=\dfrac{-47}{36}\)
2/3 - 5/3 : 3/4 + 25%
= 2/3 - 20/9 + 1/4
= -47/36
\(\dfrac{2}{3}-\dfrac{5}{3}:\dfrac{3}{4}+25\%\\ =\dfrac{2}{3}-\dfrac{5}{3}\cdot\dfrac{4}{3}+\dfrac{1}{4}\\ =\dfrac{2}{3}-\dfrac{20}{3}+\dfrac{1}{4}\\ =-6+\dfrac{1}{4}\\ =-\dfrac{23}{4}\)
