Question

Tính

\(3\dfrac{1}{3}-\left(4\dfrac{2}{5}+1\dfrac{1}{3}\right)\)

Answer 1

=\(\dfrac{10}{3}-\left(\dfrac{22}{5}+\dfrac{4}{3}\right)\)

=\(\dfrac{10}{3}-\dfrac{86}{15}\)

=\(-\dfrac{12}{5}\)

Answer 2

Ta có: \(3\dfrac{1}{3}-\left(4\dfrac{2}{5}+1\dfrac{1}{3}\right)\)

\(=\dfrac{10}{3}-\dfrac{22}{5}-\dfrac{4}{3}\)

\(=2-\dfrac{22}{5}=-\dfrac{12}{5}\)

Answer 3

= 10/9 -( 22/5+4/3)

=10/9 - (66/15+20/15)

=10/9 - 86/15

=50/45 - 258/15

= -203/15
