Question

Tính bằng cách thuận tiện ;

\(\frac{1}{2}\)\(\div\)\(\frac{1}{5}\)\(+\)\(\frac{1}{3}\)\(\div\)\(\frac{1}{5}\)\(+\)\(\frac{1}{6}\)\(\div\)\(\frac{1}{5}\)

Answer 1

(\(\frac{1}{2}\):\(\frac{1}{3}\):\(\frac{1}{6}\)) +\(\frac{1}{5}\)

= 9 +  \(\frac{1}{5}\)

=\(\frac{46}{5}\)

K minh nhe ban

Answer 2

\(\frac{1}{2}:\frac{1}{5}+\frac{1}{3}:\frac{1}{5}+\frac{1}{6}:\frac{1}{5}\)

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

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

\(=1:\frac{1}{5}\)

\(=1\times5\)

\(=5\)

Answer 3

\(\frac{1}{2}:\frac{1}{5}+\frac{1}{3}:\frac{1}{5}+\frac{1}{6}:\frac{1}{5}\)

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

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

\(=1:\frac{1}{5}\)

\(=1\times5\)

\(=5\)
