= 11/125 - [(17/18 - 4/9) + (5/7 - 17/14)]
= 11/125 - (1/2 - 1/2)
= 11/125
\(\dfrac{11}{125}-\dfrac{17}{18}-\dfrac{5}{7}+\dfrac{4}{9}+\dfrac{17}{14}=\dfrac{11}{125}-\left(\dfrac{17}{18}-\dfrac{4}{9}\right)+\left(\dfrac{17}{14}-\dfrac{5}{7}\right)=\dfrac{11}{125}-\dfrac{17-4.2}{18}+\dfrac{17-5.2}{14}=\dfrac{11}{125}-\dfrac{9}{18}+\dfrac{7}{14}=\dfrac{11}{125}-\dfrac{1}{2}+\dfrac{1}{2}=\dfrac{11}{125}\)
11/125 - 17/18 - 5/7 + 4/9 + 17/14
=11/125 - (17/18 - 4/9) - (5/7 -17/14)
=11/125 - (17/18 - 8/18) - (10/14 - 17/14)
=11/125 - 9/18 + 7/14
=11/125 - 1/2 + 1/2
=11/125 (= 0,88)
a) \(=\left(\left(-\frac{1}{4}-\frac{5}{3}\right)+\frac{7}{33}\right)-\left(-\frac{15}{12}+\frac{6}{11}-\frac{48}{49}\right)\)
\(=\left(-\frac{23}{12}+\frac{7}{33}\right)+\frac{15}{12}-\frac{6}{11}+\frac{48}{49}\)
\(=\left(-\frac{23}{12}+\frac{15}{12}\right)+\left(\frac{9}{33}-\frac{6}{11}\right)+\frac{48}{49}\)
\(=-\frac{2}{3}-\frac{3}{11}+\frac{48}{49}\)
\(=\frac{65}{1617}\)
b) \(=\frac{11}{125}+\left(-\frac{17}{18}+\frac{4}{9}\right)+\left(-\frac{5}{7}+\frac{17}{14}\right)\)
\(=\frac{11}{125}-\frac{1}{2}+\frac{1}{2}\)
\(=\frac{11}{125}\)
a) \(\frac{11}{125}-\frac{17}{18}-\frac{5}{7}+\frac{4}{9}+\frac{17}{14}\)

\(\frac{11}{125}-\frac{17}{18}-\frac{5}{7}+\frac{4}{9}+\frac{17}{14}\)
= \(\frac{11}{125}-\left(\frac{17}{18}-\frac{4}{9}\right)-\left(\frac{5}{7}-\frac{17}{14}\right)\)
= \(\frac{11}{125}-\left(\frac{17}{18}-\frac{8}{18}\right)-\left(\frac{10}{14}-\frac{17}{14}\right)\)
= \(\frac{11}{125}-\frac{1}{2}+\frac{1}{2}\)
= \(\frac{11}{125}\)
A) 11/125+(-17/18+4/9)-(5/7-17/14)
=11/125+(-17/18+8/18)-(10/14-17/14)
=11/125+(-1/2)-(-1/2)
=11/125
\(\frac{11}{125}-\frac{17}{18}-\frac{5}{7}+\frac{4}{9}+\frac{17}{14}\)
\(=\frac{11}{125}+\left(\frac{-17}{18}+\frac{4}{8}\right)+\left(\frac{-5}{7}+\frac{17}{14}\right)\)
\(=11+\left(\frac{-17}{18}+\frac{8}{18}\right)+\left(\frac{-10}{14}+\frac{17}{14}\right)\)
\(=\frac{11}{125}+\left(\frac{-9}{18}\right)+\frac{7}{14}\)
\(=\frac{11}{125}+\left(\frac{-1}{2}+\frac{1}{2}\right)\)
\(=\frac{11}{125}+0\)
\(=\frac{11}{125}\)
