\(\frac{3}{4}+\frac{1}{4}:\frac{1}{2}=\frac{3}{4}+\frac{1}{2}=\frac{5}{4}\) nha bạn
\(\frac{3}{4}+\frac{1}{4}:\frac{1}{2}\)
= \(\frac{3}{4}+\frac{1}{4}\times\frac{2}{1}\)
= \(\frac{3}{4}+\frac{1}{2}\)
= \(\frac{5}{4}\)
\(\frac{3}{4}+\frac{1}{4}\): \(\frac{1}{2}\)
\(=\frac{3}{4}+\frac{1}{4}\cdot\frac{2}{1}\)
\(=\frac{3}{4}+\frac{2}{4}\)
\(=\frac{5}{4}\)
