Question

x chia 2 công x cộng x chia 3 cộng x chia 4 =25

 

Answer 1

\(\frac{x}{2}+\frac{x}{3}+\frac{x}{4}=25\)

\(x\times\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{4}\right)=25\)

\(x\times\frac{13}{12}=25\)

\(x=25:\frac{13}{12}\)

x = 300/13

Answer 2

\(x\div2+x\div3+x\div4=25\)

\(x\div\left(2+3+4\right)=25\)

\(x\div9=25\)

\(x=25\times9\)

\(x=225\).

Answer 3

X : 2 + X + X : 3 + X : 4 = 25                                                                                                                                                                          X x 1/2 + X x1 + X x 1/3 + X x 1/4 = 25

X x(1/2+1+1/3+1/4) =25

X x 25/12 = 25

X              = 25 : 25/12

X              =12

Answer 4

\(\frac{x}{2}+\frac{x}{3}+\frac{x}{4}=25\)

\(x.\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{4}\right)=25\)

\(x.\left(\frac{6}{12}+\frac{4}{12}+\frac{3}{12}\right)=25\)

\(x.\frac{13}{12}=25\)

\(x=25:\frac{13}{12}\)

\(x=25.\frac{12}{13}\)

\(x=\frac{300}{13}\)

Vậy \(x=\frac{300}{13}\)

Answer 5

\(\frac{x}{2}+\frac{x}{3}+\frac{x}{4}=25\)

\(\Rightarrow x\times\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{4}\right)=25\)

\(\Rightarrow x\times\frac{13}{12}=25\)

\(\Rightarrow x=25\div\frac{13}{12}\)

\(\Rightarrow x=\frac{300}{13}\)

Vậy \(x=\frac{300}{13}\)
