tíc cho mình nha

2/3 - 7/24 = 3/8 

\(\frac{2}{3}-\left(\frac{1}{6}+\frac{1}{8}\right)\)=\(\frac{16}{24}-\left(\frac{4}{24}+\frac{3}{24}\right)\)=\(\frac{16}{24}-\frac{7}{24}=\frac{9}{24}=\frac{3}{8}\)

33/35 - 12/35

=3/5

= 3/5 x ( 11/7 - 4/7)

= 3/5 x 1

= 3/5

Vậy...

\(\dfrac{3}{5}\)

5 . 4² - 18 : 3 + 3² . 3

= 5 . 16 - 18 : 3 + 9 . 3

= 80 - 6 + 27

= 74 + 27

= 101

\(5\text{.}4^2-18:3+3^2.3\)

= 5. 16 - 6 + 27

= 80+ 21

= 101

3+4+5x4+23=50

\(3+4+5\times4+23\)

\(=3+4+20+23\)

\(=7+20+23\)

\(=27+23\)

\(=50\)

3+5x4:2x3:9-9= \(\frac{-8}{3}\)

Sai đề nha!

sai đề rồi

1-3/5

=5/5-3/5

=2/5

3/5*4/7

=12/35

2/5 >12/35

nho ****

-6/35

1/5x (4/7- 3/7- 1)=1/5x -6/7= -6/35

\(-\dfrac{6}{35}\)

\(\dfrac{1}{5}\times\dfrac{4}{7}+\dfrac{3}{7}\times\dfrac{1}{5}-\dfrac{1}{5}\)

\(=\dfrac{4}{35}+\dfrac{3}{35}-\dfrac{1}{5}\)

\(=\dfrac{7}{35}-\dfrac{1}{5}\)

\(=\dfrac{1}{5}-\dfrac{1}{5}\)

\(=0\)
