Question

Tính : ( 4/3 -2/3 - 9/8 ) : ( 1 - 4/5 )

Ai làm nhanh và đúng mình tick cho

Answer 1

\(\left(\frac{4}{3}-\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)

\(=\left(\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)

\(=-\frac{11}{24}:\frac{1}{5}\)

\(=-\frac{55}{24}\)

Answer 2

-55/24

Answer 3

(4/3-2/3-9/8):(1-4/5)

=-11/24:1/5

=-79/120

k cho mk nhé,bn hok tốt

Answer 4

\(\left(\frac{4}{3}-\frac{2}{3}-\frac{9}{8}\right)\div\left(1-\frac{4}{5}\right)\)

\(\left(\frac{2}{3}-\frac{9}{8}\right)\div\left(\frac{5}{5}-\frac{4}{5}\right)\)

\(\left(\frac{16}{24}-\frac{27}{24}\right)\div\frac{1}{5}\)

\(\frac{-11}{24}\div\frac{1}{5}\)

\(-\frac{11}{24}\times5\)

\(-\frac{55}{24}\)

Answer 5

\(\left(\frac{4}{3}-\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)   

= \(\left(\frac{32}{24}-\frac{16}{24}-\frac{27}{24}\right):\left(\frac{5}{5}-\frac{4}{5}\right)\) 

=  \(\left(\frac{32-16-27}{24}\right).\frac{5}{1}\)  

=   \(\frac{-11}{24}.5\)

= \(\frac{-55}{24}\)

Answer 6

\(\left(\frac{4}{3}-\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)

\(=\left(\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)

\(=-\frac{11}{24}:\frac{1}{5}\)

\(=-\frac{55}{24}\)
