Question

5 phần 6 - 4 phần 9 chia 8

Answer 1

= 7/9

Answer 2

\(=\frac{7}{9}\\\)

Answer 3

\(\dfrac{5}{6}-\dfrac{4}{9}:8=\dfrac{5}{6}-\dfrac{1}{18}=\dfrac{15}{18}-\dfrac{1}{18}=\dfrac{14}{18}=\dfrac{7}{9}\)

Answer 4

21/432

Answer 5

7/9

Answer 6

\(\dfrac{5}{6}-\left(\dfrac{4}{9}:\dfrac{8}{1}\right)=\dfrac{5}{6}-\left(\dfrac{4}{9}\times\dfrac{1}{8}\right)=\dfrac{5}{6}-\dfrac{4}{72}=\dfrac{5}{6}-\dfrac{1}{18}=\dfrac{15}{18}-\dfrac{1}{18}=\dfrac{14}{18}=\dfrac{7}{9}\)

Answer 7

= 7/9

Answer 8

    \(\dfrac{5}{6}-\dfrac{4}{9}\div8\)

\(=\dfrac{5}{6}-\dfrac{4}{9}\times\dfrac{1}{8}\)

\(=\dfrac{5}{6}-\dfrac{1}{18}=\dfrac{15}{18}-\dfrac{1}{18}=\dfrac{14}{18}\)

Rút gọn: \(\dfrac{7}{9}\)
