198/100
\(\frac{8}{10}+\frac{9}{100}+\frac{10}{10}\) \(=\)\(1\frac{89}{100}\)
nha bn
8/10+9/100+10/10=189/100
hok tốt
8/10 + 9/100 +10/10
=0,8+0,09+1
=0,89+1
=1.89 hoặc 189/100
=80/100+9/100+1
=189/100
=1,89
\(\frac{8}{10}\) + \(\frac{9}{100}\)+ \(\frac{10}{10}\)
= \(\frac{80}{100}\) + \(\frac{9}{100}\)+ 1
= \(\frac{189}{100}\).
