Question

tính:

-4/9.3/11+-4/9.8/11+-5/9

nhanh ạ, mik đag cần gấp

Answer 1

\(\frac{-4}{9}.\frac{3}{11}+\frac{-4}{9}.\frac{8}{11}+\frac{-5}{9}\)

=\(\frac{-4}{9}.\left(\frac{3}{11}+\frac{8}{11}\right)+\frac{-5}{9}\)

=\(\frac{-4}{9}.1+\frac{-5}{9}\)

=\(\frac{-4}{9}+\frac{-5}{9}\)

=\(\frac{-9}{9}\)=\(-1\)

Nhớ tick cho mik nha

Answer 2

\(\frac{-4}{9}.\frac{3}{11}+\frac{-4}{9}.\frac{8}{11}+\frac{-5}{9}\)

= \(\frac{-4}{9}.\left(\frac{3}{11}+\frac{8}{11}\right)+\frac{-5}{9}\)

= \(\frac{-4}{9}.1+\frac{-5}{9}\)

= \(\frac{-4}{9}+\frac{-5}{9}\)

= -1
