Question

Tính:

\(\dfrac{5}{12}.\dfrac{4}{11}-\dfrac{4}{11}+\dfrac{7}{12}.\dfrac{4}{11}\)

Answer 1

\(=\dfrac{4}{11}\left(\dfrac{5}{12}-1+\dfrac{7}{12}\right)=\dfrac{4}{11}\cdot0=0\)

Answer 2

0

Answer 3

\(\dfrac{5}{12}.\dfrac{4}{11}-\dfrac{4}{11}+\dfrac{7}{12}.\dfrac{4}{11}\)

\(=\dfrac{4}{11}.\left(\dfrac{5}{12}-1+\dfrac{7}{12}\right)\)

\(=\dfrac{4}{11}.\left(\dfrac{5}{12}-\dfrac{12}{12}+\dfrac{7}{12}\right)\)

\(=\dfrac{4}{11}.\left(\dfrac{-7}{12}+\dfrac{7}{12}\right)\)

\(=\dfrac{4}{11}.\dfrac{0}{12}\)

\(=\dfrac{4}{11}.0\)

\(=0\)

Answer 4

kq =0 nha

chúc bạn học tốt

Answer 5

\(\dfrac{5}{12}\cdot\dfrac{4}{11}-\dfrac{4}{11}+\dfrac{7}{12}\cdot\dfrac{4}{11}\)

\(=\dfrac{4}{11}\cdot1-\dfrac{4}{11}\)

=0

Answer 6

=0
