Question

A (3/4-1/2) x 2/7 B 2/9:(1+1/2)2 C 3 1/2:5 2/5+7 POR FAVOR ME AJUDEM

Answer 1

$(\frac{3}{4} - \frac{1}{2}) \times \frac{2}{7} = \frac{4}{8} \times \frac{2}{7} = \frac{8}{56} \\ \\ \frac{2}{8} ( \frac{1}{1} + \frac{1}{2} ) = \frac{2}{9} \div \frac{3}{3} = \frac{6}{27} \\ \\ \frac{1}{2} \times \frac{1}{5} \times \frac{2}{5} + \frac{7}{1} = \frac{1}{10} \times \frac{37}{5} = \frac{37}{50}$
