\(=\frac{37}{53}x\frac{23}{48}x\frac{53}{37}x\frac{24}{23}\)
\(=\left(\frac{37}{53}x\frac{53}{37}\right)x\left(\frac{23}{48}x\frac{24}{23}\right)\)
\(=1x\frac{24}{48}\)
\(=1x\frac{1}{2}\)
\(=\frac{1}{2}\)
37/53 x 23/48 x 535353/373737x242424/232323= 1/5 =0,5
ta có: \(\frac{535353}{373737}=\frac{535353\div10101}{373737\div10101}=\frac{53}{37}\)
và \(\frac{242424}{232323}=\frac{242424\div10101}{232323\div10101}=\frac{24}{23}\)
Vậy \(\frac{37}{53}\times\frac{23}{48}\times\frac{53}{37}\times\frac{24}{23}\)
\(=\frac{37\times23\times53\times24}{53\times48\times37\times23}\)
\(=\frac{24}{48}\)
\(=\frac{1}{2}\)
\(\frac{37}{53}\cdot\frac{23}{48}\cdot\frac{53}{37}\cdot\frac{24}{23}\)
\(=(\frac{37}{53}\cdot\frac{23}{48})\cdot(\frac{53}{37}\cdot\frac{24}{23})\)
\(=1\cdot\frac{24}{48}\)
\(=1\cdot\frac{1}{2}\)
\(=\frac{1}{2}\)
