Phuong lê thảo thanh đây nhé!
\(x+\frac{1}{2}\cdot\frac{1}{5}=\frac{3}{4}\)
\(\Leftrightarrow x+\frac{1}{10}=\frac{3}{4}\)
\(\Leftrightarrow x=\frac{3}{4}-\frac{1}{10}\)
\(\Leftrightarrow x=\frac{15}{20}-\frac{2}{20}=\frac{13}{20}\)
Vậy x=\(\frac{13}{20}\)
\(x+\frac{1}{2}\)\(\times\frac{1}{5}\)\(=\frac{3}{4}\)
\(x+\frac{1}{10}\) \(=\frac{3}{4}\)
\(x=\frac{3}{4}-\frac{1}{10}\)
\(x=\frac{13}{20}\)
Vậy \(x=\frac{13}{20}\)
Hok tốt !
X + 1/2x1/5 =3/4
X+1/10=3/4
X=3/4-1/10
X=13/20
Cảm ơn các bạn
