\(\dfrac{11}{24}-\dfrac{5}{41}+\dfrac{13}{24}+0,5-\dfrac{36}{41}\)
\(=\dfrac{11}{24}-\dfrac{5}{41}+\dfrac{13}{24}+\dfrac{1}{2}-\dfrac{36}{41}\)
\(=\left(\dfrac{11}{24}+\dfrac{13}{24}\right)-\left(\dfrac{5}{41}+\dfrac{36}{41}\right)+\dfrac{1}{2}\)
\(=1-1+\dfrac{1}{2}\)
\(=0+\dfrac{1}{2}\)
\(=\dfrac{1}{2}\)
-----------------------------------------
\(\dfrac{1}{3}-\dfrac{1}{3}.\left(2-\dfrac{7}{4}\right)^2\)
\(=\dfrac{1}{3}-\dfrac{1}{3}.\left(\dfrac{1}{4}\right)^2\)
\(=\dfrac{1}{3}-\dfrac{1}{3}.\dfrac{1}{16}\)
\(=\dfrac{1}{3}-\dfrac{1}{48}\)
\(=\dfrac{16}{48}-\dfrac{1}{48}\)
\(=\dfrac{5}{16}\)
a: \(=\dfrac{11}{24}+\dfrac{13}{24}-\dfrac{5}{41}-\dfrac{36}{41}+\dfrac{1}{2}=\dfrac{1}{2}\)
b: \(=\dfrac{1}{3}-\dfrac{1}{3}\cdot\left(\dfrac{1}{4}\right)^2=\dfrac{1}{3}\cdot\dfrac{15}{16}=\dfrac{5}{16}\)
