Question

Tìm x :

x/13:15/16=46/52 

Answer 1

\(\frac{x}{13}:\frac{15}{16}=\frac{46}{52}\)

\(\Rightarrow\frac{x}{13}=\frac{46}{52}\cdot\frac{15}{16}=\frac{23}{26}\cdot\frac{15}{16}\)

\(\Rightarrow\frac{x}{13}=\frac{345}{416}\)

\(\Rightarrow x=\frac{345}{416}\cdot13=\frac{345}{32}\)

Vậy \(x=\frac{345}{32}\)

Answer 2

\(\frac{x}{13}:\frac{15}{16}=\frac{46}{52}\)

\(\Rightarrow\frac{x}{13}:\frac{15}{16}=\frac{23}{26}\)

\(\Rightarrow\frac{x}{13}=\frac{23}{26}\times\frac{15}{16}\)

\(\Rightarrow\frac{x}{13}=\frac{345}{416}\)

\(\Leftrightarrow416\times x=13\times345\)

\(\Rightarrow416\times x=4485\)

\(\Rightarrow x=4485:416\)

\(\Rightarrow x=\frac{345}{32}\)

Answer 3

\(\frac{x}{13}\div\frac{15}{16}=\frac{46}{52}\)

\(\Rightarrow\frac{x}{13}\div\frac{15}{16}=\frac{23}{26}\)

\(\Rightarrow x\div13=\frac{345}{416}\)

\(\Rightarrow x=\frac{345}{52}\)

Answer 4

\(\frac{X}{13}:\frac{15}{16}=\frac{46}{52}\)

<=> \(\frac{X}{13}.\frac{16}{15}=\frac{46}{52}\)

<=> \(\frac{x}{13}=\frac{345}{416}\)

<=> \(X=\frac{345}{32}\left(\approx10,78\right)\)

Answer 5

\(\frac{x}{13}:\frac{15}{16}=\frac{46}{52}\)

\(\Leftrightarrow\frac{x}{13}=\frac{46}{52}.\frac{15}{16}\)

\(\Leftrightarrow x:13=\frac{345}{416}\)

\(\Leftrightarrow x=\frac{345}{416}.13\)

\(\Leftrightarrow x=\frac{345}{32}\)
