Answer 1

\(\frac{1919}{2323}.\frac{4646}{7474}.\frac{37}{19}\)

\(=\frac{19}{23}.\frac{23}{37}.\frac{37}{19}\)

\(=\frac{19.23.37}{23.37.19}\)

\(=1\)

Answer 2

ta có:

 \(\frac{1919}{2323}=\frac{19}{23}\)

\(\frac{4646}{7474}=\frac{46}{74}\)

=> \(\frac{1919}{2323}\cdot\frac{4646}{7474}.\frac{37}{19}=\frac{19}{23}\cdot\frac{46}{74}\cdot\frac{37}{19}\)= \(\frac{19}{23}\cdot\frac{2\cdot23}{37\cdot2}\cdot\frac{37}{19}\)= 1
