Question

\(\frac{9}{14}\cdot y=\frac{7}{14}\cdot\frac{4}{7}\)

Answer 1

\(\frac{9}{14}.y=\frac{7.4}{14.7}\)

\(\frac{9}{14}.y=\frac{1.2}{7.1}\)

\(\frac{9}{14}.y=\frac{2}{7}\)

\(y=\frac{2}{7}:\frac{9}{14}=\frac{2}{7}.\frac{14}{9}\)

\(y=\frac{2.2}{1.9}=\frac{4}{9}\)

Đúng 100%

Answer 2

Ta có : \(\frac{9}{14}y=\frac{7}{14}.\frac{4}{7}\)

\(\Rightarrow\frac{9}{14}y=\frac{2}{7}\)

\(\Rightarrow y=\frac{2}{7}.\frac{14}{9}\)

\(\Rightarrow y=\frac{4}{9}\)

Answer 3

\(\frac{9}{14}\cdot y=\frac{7}{14}\cdot\frac{4}{7}\)

\(\frac{9}{14}\cdot y=\frac{2}{7}\)

        \(y=\frac{2}{7}:\frac{9}{14}\)

        \(y=\frac{4}{9}\)

Answer 4

\(\frac{9}{14}.y=\frac{7}{14}.\frac{4}{7}\)

\(\frac{9}{14}.y=\frac{1}{7}\)

\(y=\frac{1}{7}:\frac{9}{14}\)

\(y=\frac{9}{98}\)

Answer 5

\(\Rightarrow\frac{9}{14}.y=\frac{4}{14}\)

\(\Rightarrow y=\frac{4}{14}:\frac{9}{14}=\frac{4}{9}\)

Answer 6

9/14 x y = 2/7

y = 2/7 : 9/14

y = 4/9

Answer 7

9/14.y = 7/14.4/7

9/14.y = 2/7

       y = 2/7 : 9/14

       y = 4/9

vậy y = 4/9

tk mk nhé,mk đầu tiên

Answer 8

\(\frac{9}{14}\cdot y=\frac{7}{14}\cdot\frac{4}{7}\)

\(\frac{9}{14}\cdot y=\frac{2}{7}\)

        \(y=\frac{2}{7}:\frac{9}{14}\)

        \(y=\frac{4}{9}\)

Answer 9

4/9
