Question

tìm x, biết: \(2\frac{3}{4}x=3\frac{1}{7}:0,01\)

Answer 1

\(2\frac{3}{4}x=3\frac{1}{7}:0,01\)

\(\Leftrightarrow\frac{11}{4}x=\frac{22}{7}:\frac{1}{100}\)

\(\Leftrightarrow\frac{11}{4}x=\frac{2200}{7}\)

\(\Leftrightarrow x=\frac{2200}{7}:\frac{11}{4}\)

\(\Leftrightarrow x=\frac{800}{7}\)

Vậy ..................

Answer 2

\(2\frac{3}{4}x=3\frac{1}{7}:0,01\)

\(\Rightarrow\frac{11}{4}x=\frac{22}{7}:\frac{1}{100}\)

\(\Rightarrow\frac{11}{4}x=\frac{2200}{7}\)

\(\Rightarrow x=\frac{2200}{7}:\frac{11}{4}\)

\(\Rightarrow x=\frac{800}{7}\)

Vậy \(x=\frac{800}{7}.\)
