\(40\dfrac{1}{2}+\left(37\dfrac{1}{3}-25\dfrac{1}{2}\right)-13\dfrac{1}{3}\)

Answer 1

\(40\dfrac{1}{2}+\left(37\dfrac{1}{3}-25\dfrac{1}{2}\right)-13\dfrac{1}{3}\)

\(=\left(40\dfrac{1}{2}-25\dfrac{1}{2}\right)+\left(37\dfrac{1}{3}-13\dfrac{1}{3}\right)\)

\(=25+14\)

\(=39\)

Answer 2

=\(\left(40\dfrac{1}{2}-25\dfrac{1}{2}\right)+\left(37\dfrac{1}{3}-13\dfrac{1}{3}\right)\)

\(=25+14\)

=39
