Answer 2

\(\frac{(2}{3}\)\(+\frac{1)}{2}\)x \(\frac{9}{4}\): 2

=   7 x 9 : 2 =

     6    4

= 82 : 2

   24

= 82

   48

k nha

Answer 3

\(\left(\frac{2}{3}+\frac{1}{2}\right)\cdot\frac{9}{4}:2\)

\(\Leftrightarrow\left(\frac{4}{6}+\frac{3}{6}\right)\cdot\left(\frac{9}{4}\cdot\frac{1}{2}\right)\)

\(\Rightarrow\frac{7}{6}\cdot\frac{9}{8}\)

\(\Rightarrow\frac{63}{48}=\frac{21}{16}\)

Answer 4

bằng \(\frac{21}{16}\)

hok tốt nha

k mình với

huhuhu

ok nhaaaaaaaaaa

Answer 5

\(=\left(\frac{4}{6}+\frac{3}{6}\right)X\frac{9}{8}\)

\(=\frac{7}{6}X\frac{9}{8}=\frac{63}{48}=\frac{21}{16}\)

Answer 6

=  (  4/6 + 3/6 ) x 9/4 :2

=    7/6  x  9/4  :2

=   63/ 24 : 2/1

= 63 /24  x 1/2

=  63 / 48   =   21 /16

Answer 7

\(\left(\frac{2}{3}+\frac{1}{2}\right)\times\frac{9}{4}\div2\)

\(=\left(\frac{4}{6}+\frac{3}{6}\right)\times\left(\frac{9}{4}\times\frac{1}{2}\right)\)

\(=\frac{7}{6}\times\frac{9}{8}\)

\(=\frac{21}{16}\)

Nếu đúng thì ấn đùng giùm mk nhé 

Answer 8

\(\left(\frac{2}{3}+\frac{1}{2}\right)x\frac{9}{4}:2\)

= \(\left(\frac{4}{6}+\frac{3}{6}\right)x\left(\frac{9}{4}x\frac{1}{2}\right)\)

= \(\frac{7}{6}\)x\(\frac{9}{8}\)

= \(\frac{63}{48}\)

= \(\frac{21}{16}\)

Answer 9

\(\left(\frac{2}{3}+\frac{1}{2}\right)\times\frac{9}{4}\)\(:\)\(2\)

\(=\left(\frac{4}{6}+\frac{3}{6}\right)\times\left(\frac{9}{4}\times\frac{1}{2}\right)\)

\(=\frac{7}{6}\times\frac{9}{8}\)

\(=\frac{63}{48}=\frac{21}{16}\)
