x0x0x : X x 3 – 20202
= 10101 x 3 – 20202
= 30303 – 20202
= 10101
x0x0x : X x 3 - 20202
= 10101 x 3 - 20202
= 30303 - 20202
= 10101
Chúc bạn học giỏi
1) \(=\left(\frac{3}{5}+\frac{2}{5}\right).\frac{6}{11}\)
\(=1.\frac{6}{11}\)
\(=\frac{6}{11}\)
2)\(\frac{17}{25}.\left(\frac{11}{19}+\frac{6}{19}+\frac{2}{19}\right)\)
\(=\frac{17}{25}.1\)
\(=\frac{17}{25}\)
\(x-\frac{1}{4}=\frac{3}{5}\)
\(x=\frac{3}{5}+\frac{1}{4}\)
\(x=\frac{12}{20}+\frac{5}{20}\)
\(x=\frac{17}{20}\)
\(x:\frac{2}{3}=\frac{1}{2}\)
\(x=\frac{1}{2}.\frac{2}{3}\)
\(x=\frac{1}{3}\)

\(x-\frac{1}{4}=\frac{3}{5}\)
\(x\) \(=\frac{3}{5}+\frac{1}{4}\)
\(x\) \(=\frac{12}{20}+\frac{5}{20}\)
\(x\) \(=\frac{17}{20}\)
\(x:\frac{2}{3}=\frac{1}{2}\)
\(x\) \(=\frac{1}{2}x\frac{2}{3}\)
\(x\) \(=\frac{2}{6}\)rút gọn \(\frac{1}{3}\)
\(x+\frac{3}{4}=\frac{5}{3}\)
\(x=\frac{5}{3}-\frac{3}{4}\)\(=\frac{20}{12}-\frac{9}{12}\)
\(x=\frac{11}{12}\)
\(x-\frac{2}{3}=\frac{7}{2}\)
\(x=\frac{7}{2}+\frac{2}{3}\)\(=\frac{21}{6}+\frac{4}{6}\)
\(x=\frac{25}{6}\)
