\(\frac{3}{4}\times\frac{2}{9}+\frac{1}{3}\)
\(=\frac{1}{6}+\frac{1}{3}\)
\(=\frac{3}{18}+\frac{6}{18}=\frac{1}{2}\)
a) \(\frac{3}{4}\cdot\frac{2}{9}+\frac{1}{3}=\frac{1}{2}\)
b)\(\frac{1}{4}:\frac{1}{3}-\frac{1}{2}=\frac{1}{4}\)
\(\frac{3}{4}X\)\(\frac{2}{9}\)\(+\frac{1}{3}\)
\(\frac{1}{6}+\frac{1}{3}\)
=\(\frac{1}{2}\)
\(\frac{1}{4}:\frac{1}{3}-\frac{1}{2}\)
\(=\frac{3}{4}-\frac{1}{2}\)
\(=\frac{1}{4}\)
