Question

Tính giá trị biểu thức:

\(\dfrac{7}{8}\) - \(\dfrac{4}{9}\) : \(\dfrac{2}{3}\) =

Answer 1

=7/8-2/3=21/16

Answer 2

\(\dfrac{7}{24}\)

Answer 3

7/8 - 2/3 = 5/24

Answer 4

\(\dfrac{7}{8}-\dfrac{4.3}{2.9}=\dfrac{7}{8}-\dfrac{2}{3}=\dfrac{21-16}{24}=\dfrac{5}{24}\)

Answer 5

\(=\dfrac{7}{8}-\dfrac{2}{3}=\dfrac{5}{24}\)

Answer 6

21/16

Answer 7

\(\dfrac{7}{8}-\dfrac{4}{9}:\dfrac{2}{3}=\dfrac{7}{8}-\dfrac{4}{9}\times\dfrac{3}{2}=\dfrac{7}{8}-\dfrac{2}{3}=\dfrac{21}{24}-\dfrac{16}{24}=\dfrac{5}{24}\)

Answer 8

Tính giá trị biểu thức:

7/8 - 4/9 : 2/3 = 7/8 - ( 4/9 : 2/3 )

= 7/8 - ( 4/9 x 3/2 ) = 7/8 - 2/3

= 21/24 - 16/24 = 5/24.

Answer 9

7/8 - 4/9 : 2/3 = 7/8 - 2/3 = 21/24 - 16/24 = 5/24

Answer 10

5/24
