\(\text{Rút gọn BT .Ta dc:}\)
\(\frac{3}{16}+1=\frac{19}{16}\)
\(\frac{121212}{646464}+\frac{154.42+34}{156.42-50}=\frac{12}{64}+\frac{154.42+34}{154.42+84-50}=\frac{3}{16}+\frac{154.42+34}{154.42+34}=\frac{3}{6}+1=\frac{9}{6}=\frac{3}{2}\)
Bạn ơi mình viết lộn:\(\frac{3}{16}+\frac{154.42+34}{154.42+34}=\frac{3}{16}+1=\frac{19}{16}\)
