\(B=\dfrac{3}{41}-\dfrac{12}{87}+\dfrac{2}{2022}:\dfrac{9}{41}-\dfrac{16}{87}+\dfrac{36}{2022}\)

\(=\dfrac{3}{42}-\dfrac{12}{87}+\dfrac{41}{9099}-\dfrac{16}{87}+\dfrac{6}{337}\)

\(=\dfrac{3}{42}-\dfrac{28}{87}+\dfrac{41}{9099}+\dfrac{6}{337}\)

\(=-\dfrac{305}{1218}+\dfrac{41}{9099}+\dfrac{6}{337}\)

\(=-0,245+\dfrac{6}{337}\)

\(=-0,227\)
