Question

simplify-
2/5_7+3_14–13_21​

Answer 1

It's 2.3095......

$2 \frac{5}{7} + \frac{3}{14} - \frac{13}{21} \\ = \frac{19}{7} + \frac{3}{14} - \frac{13}{21} \\ = \frac{57 - 13}{21} + \frac{3}{14} \\ = \frac{44}{21} + \frac{3}{14} \\ = \frac{1}{7} ( \frac{44}{3} + \frac{3}{2} ) \\ = \frac{1}{7} ( \frac{88 + 9}{6} ) \\ = \frac{1}{7} ( \frac{97}{6} ) = \frac{97}{42}≈2.3095$
