Question

Tím x:

A.x*3,14=3,768

B.2/3*x=1/4

Answer 1

\(a,x\times3,14=3,768\)

\(\Leftrightarrow x=3,768:3,14\)

\(\Leftrightarrow x=1,2\)

\(b,\dfrac{2}{3}\times x=\dfrac{1}{4}\)

\(\Leftrightarrow x=\dfrac{1}{4}:\dfrac{2}{3}\)

\(\Leftrightarrow x=\dfrac{1}{4}\times\dfrac{3}{2}\)

\(\Leftrightarrow x=\dfrac{3}{8}\)
