Question

Tìm x:

x - 1/4 = 5/3 

x : 5/11 = 22 

2/4 + x = 1 

x - 11/5 = 2/5 : 2/3 

Nhanh nhé!!!

Answer 1

\(x-\frac{1}{4}=\frac{5}{3}\)

\(\Rightarrow x=\frac{23}{12}\)

\(x:\frac{5}{11}=22\)

\(\Rightarrow x=10\)

\(\frac{2}{4}+x=1\)

\(\Rightarrow x=\frac{1}{2}\)

\(x-\frac{11}{5}=\frac{2}{5}:\frac{2}{3}\)

\(\Rightarrow x-\frac{11}{5}=\frac{3}{5}\)

\(\Rightarrow x=\frac{18}{5}\)

Answer 2

\(a)x-\frac{1}{4}=\frac{5}{3}\)

\(\Rightarrow x=\frac{5}{3}+\frac{1}{4}=\frac{23}{12}\)

\(b)x:\frac{5}{11}=22\)

\(\Rightarrow x=22.\frac{5}{11}=10\)

\(c)\frac{2}{4}+x=1\)

\(x=1-\frac{2}{4}=\frac{1}{2}\)

\(d)x-\frac{11}{5}=\frac{2}{5}:\frac{2}{3}\)

\(\Rightarrow x-\frac{11}{5}=\frac{3}{5}\)

\(\Rightarrow x=\frac{3}{5}+\frac{11}{5}=\frac{14}{5}\)
