Question

( 7/9 - 1/2 ) -  ( 1/2 - 2/9 )

Tính nhanh nha các bạn ai nhanh nhất mik k cho

Answer 1

Ta có:

  (7/9 - 1/2) - (1/2 - 2/9)

= (14/18 - 9/18) - (9/18 - 4/18)

=       5/18        -     5/18

=               0/0

=                0.

Answer 2

\(\left(\frac{7}{9}-\frac{1}{2}\right)-\left(\frac{1}{2}-\frac{2}{9}\right)=\frac{7}{9}-\frac{1}{2}-\frac{1}{2}+\frac{2}{9}=\left(\frac{7}{9}+\frac{2}{9}\right)-\left(\frac{1}{2}+\frac{1}{2}\right)=1-1=0\)

Answer 3

=  \(\left(\frac{14}{18}-\frac{9}{18}\right)-\left(\frac{9}{18}-\frac{4}{18}\right)\)

=  \(\frac{5}{18}-\frac{5}{18}\)

=  \(1\)
