ai tra loi nhanh nhat minh se tang cho nguoi do tap truyen tranh bo moi mua cho minh

Answer 1

\(a,\text{ }\frac{1}{2}+\frac{1}{3}\text{ : }\frac{1}{6}\)

\(=\frac{1}{2}+\frac{1}{3}\cdot\frac{6}{1}\)

\(=\frac{1}{2}+\frac{6}{3}\)

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

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

\(=\frac{5}{2}\)

\(b,\text{ }\frac{1}{2}+\frac{1}{3}\cdot\frac{1}{4}\)

\(=\frac{1}{2}+\frac{1}{12}\)

\(=\frac{6}{12}+\frac{1}{12}\)

\(=\frac{7}{12}\)

Answer 10

a)\(\frac{1}{2}\)+  \(\frac{1}{3}\): \(\frac{1}{6}\)= \(\frac{1}{2}+\left(\frac{1}{3}:\frac{1}{6}\right)=\frac{1}{2}+\frac{2}{6}=\frac{3}{6}+\frac{2}{6}=\frac{5}{6}\)

b)\(\frac{1}{2}+\frac{1}{3}\times\frac{1}{4}=\left(\frac{1}{2}+\frac{1}{4}\right)\times\frac{1}{3}=\frac{3}{4}\times\frac{1}{3}=\frac{3}{12}\)
