19/37+(2-19/17)
=19/37+2-19/17
=(19/37-19/17)+2
=0+2
=2
\(\frac{19}{37}+\left(2-\frac{13}{37}\right)\)
\(=\frac{19}{37}+2-\frac{19}{37}\)
\(=\left(\frac{19}{37}-\frac{19}{37}\right)+2\)
\(=2\)
\(\frac{19}{37}+2-\frac{19}{37}\)
\(=\left(\frac{19}{37}-\frac{19}{37}\right)+2\)
\(=0+2\)
\(=2\)
\(\frac{19}{37}+\left(2-\frac{19}{37}\right)\)
\(=\frac{19}{37}+2-\frac{19}{37}\)
\(=\left(\frac{19}{37}-\frac{19}{37}\right)+2\)
\(=0+2\)
\(=0\)
Trả lời:
\(\frac{19}{37}+\left(2-\frac{19}{37}\right)\)
\(=\left(\frac{19}{37}-\frac{19}{37}\right)+2\)
\(=0+2\)
\(=2\)
