y si me ayudan jsjsj ​

Answer 1

$\frac{12}{13} \times \frac{13}{24} - 0.5 = \frac{12 \times 13}{13 \times 24} - \frac{5}{10} = \frac{1}{2} - \frac{1}{2} = 0$

$( \frac{5}{9} + \frac{1}{3} ) \div 1.7... = ( \frac{5(3) + 9(1)}{27} ) \div \frac{17 - 1}{9} \\ (\frac{15 + 9}{27} ) \div \frac{16}{9} = \frac{24}{27} \div \frac{16}{9} = \frac{8}{9} \div \frac{16}{9} \\ \frac{8}{9} \times \frac{9}{16} = \frac{1}{2}$
