Question

Answer 1

Answer:

I think you can check it in the calculator because no one will answer this

Answer 2

Step-by-step explanation:

$lhs \\ (- \frac{5}{8} + \frac{9}{4} ) + \frac{13}{16} \\ = ( \frac{ - 5 + 18}{8} ) + \frac{13}{16} \\ = \frac{13}{8} + \frac{13}{16} \\ = \frac{26 + 13}{13}$

$rhs \\ - \frac{5}{8} + ( \frac{9}{4} + \frac{13}{16} ) \\ = - \frac{5}{8} + ( \frac{36 + 13}{16} ) \\ = - \frac{5}{8} + \frac{49}{16} \\ = \frac{ - 10 + 49}{16} \\ = \frac{39}{16}$

LHS= RHS
