Question

Tìm Y

(14,17-y) * 2/9=1/3

Answer 1

(14,17 - y) . 2/9 = 1/3

14,17 - y = 1/3 : 2/9

14,17 - y = 3/2

y = 14,17 - 3/2

y = 12,67

Chúc bạn học tốt ^^

Answer 2

\(\left(14,17-y\right).\frac{2}{9}=\frac{1}{3}\)

\(\Rightarrow14,17-y=\frac{1}{3}:\frac{2}{9}\)

\(\Rightarrow14,17-y=\frac{3}{2}\)

\(y=14,17-\frac{3}{2}\)

\(y=\frac{1267}{100}=12,67\)

Answer 3

\(\left(14,17-y\right).\frac{2}{9}=\frac{1}{3}\)

\(\Rightarrow\left(14,17-y\right)=\frac{1}{3}:\frac{2}{9}=\frac{1}{3}.\frac{9}{2}=\frac{3}{2}\)

\(\Rightarrow y=14,17-\frac{3}{2}=\frac{1417}{100}-\frac{3}{2}=\frac{1417}{100}-\frac{150}{100}=\frac{1267}{100}=12,67\)

                        Vậy : \(y=12,67\)
