Question

x/5=2/3.tìm x

help meeeee

Answer 1

Ta có :

\(\dfrac{x}{5}=\dfrac{2}{3}\)

\(\Rightarrow x.3=5.2\)

\(x.3=10\)

\(x=10:3\)

\(x=\dfrac{10}{3}\)

Vậy \(x=\dfrac{10}{3}\) là giá trị cần tìm

Answer 2

Ta có :\(\dfrac{x}{5}=\dfrac{2}{3}\)

\(\Rightarrow x.3=2.5\)

\(x.3=10\)

\(x=10:3\)

\(\Rightarrow x=\dfrac{10}{3}\)

Vậy \(x=\dfrac{10}{3}\)

Vậy \(x=\dfrac{10}{3}\)

Answer 3

Ta có: \(\dfrac{x}{5}=\dfrac{2}{3}\)

=> \(3\times x=2\times5\)

\(3\times x=10\)

\(x=10\div3\)

\(x=\dfrac{10}{3}\)

Vậy \(x=\dfrac{10}{3}\)

Answer 4

\(\dfrac{x}{5}=\dfrac{2}{3}\\ \Leftrightarrow\dfrac{3x}{15}=\dfrac{10}{15}\\ \Leftrightarrow3x=10\\ \Leftrightarrow x=\dfrac{10}{3}\)

vậy phương trình có tập nghiệm là \(S=\left\{\dfrac{10}{3}\right\}\)

Answer 5

x/5 = 2/3

x * 3 = 5 * 2

x * 3 = 10

x = 10/3

Answer 6

\(\dfrac{x}{5}\) \(=\) \(\dfrac{2}{3}\)

=> \(3\) . x = \(2\) . \(5\)

=> \(3\) . x \(=\) \(10\)

x \(=\) \(10\) \(\div\) \(3\)

x \(=\) \(\dfrac{10}{3}\)

Đ/s : \(\dfrac{10}{3}\)

Answer 7

\(\dfrac{x}{5}=\dfrac{2}{3}\\ \Leftrightarrow x=\dfrac{2\cdot5}{3}\\ \Rightarrow x=\dfrac{10}{3}\)

Vậy \(x=\dfrac{10}{3}.\)

Answer 8

\(\dfrac{x}{5}=\dfrac{2}{3}\)

Vì \(\dfrac{x}{5}=\dfrac{2}{3}\) nên x.3=2.5

=> x = \(\dfrac{2.5}{3}\)

x=\(\dfrac{10}{3}\)

Vạy x=\(\dfrac{10}{3}\)

Answer 9

a) Ta có : x/5 = 2/3 => 3x = 2*5
=> 3x = 10 => x = 10/3
