\(x-\frac{10}{3}=\frac{7}{15}.\frac{3}{5}\)
\(x-\frac{10}{3}=\frac{7}{25}\)
\(x=\frac{7}{25}+\frac{10}{3}=\frac{271}{75}\)
Vậy x = 271/75
\(x-\frac{10}{3}\)\(=\)\(\frac{7}{15}\)\(.\)\(\frac{3}{5}\)
\(x-\frac{10}{3}\)\(=\) \(\frac{7}{25}\)
\(x\) \(=\)\(\frac{7}{25}\)\(+\)\(\frac{10}{3}\)
\(x\) \(=\) \(\frac{271}{75}\)
Trả lời:
x-10/3=7/15.3/5
x-10/3=7/25
x=10/3+7/25
x=271/75
x+3/22=27/121.11/9
x+3/22=3/11
x=3/11-3/22
x=3/22
1/5:x=1/2
x=1/5:1/2
x=1/5.2
x=2/5
3/5+2/5.x=1
2/5.x=1-3/5
2/5.x=2/5
x=2/5:2/5
x=1
\(x\)\(+\)\(\frac{3}{22}\)\(=\)\(\frac{27}{121}\)\(.\)\(\frac{11}{9}\)
\(x\)\(+\)\(\frac{3}{22}\)\(=\) \(\frac{3}{11}\)
\(x\) \(=\)\(\frac{3}{11}\)\(-\)\(\frac{3}{22}\)\(=\)\(\frac{3}{22}\)
