Question

x+10%.x=330

Answer 1

\(x+10\%x=330\\ x+\frac{1}{10}x=330\\\frac{11}{10}x=330\\ x=300 \)

Answer 2

\(x+10\%.x=330\)

\(x.1+0,1.x=330\)

\(x\left(1+0,1\right)=330\)

\(x.1,1=330\)

\(x=330\div1,1\)

\(x=300\)

Answer 3

\(x+10\%.x=330\)

\(\Rightarrow x+\frac{1}{10}x=330\)

\(\Rightarrow\frac{11}{10}.x=330\)

\(\Rightarrow x=330:\frac{11}{10}\)

\(\Rightarrow x=300\)

Vậy \(x=300.\)
