Question

(1/3x3/5+10/7x7/5 dividido (2- 1/2x3/4)= ajuda pfvrrrrr

Answer 1

Resposta:

$( \frac{1}{3 \div 3} \times \frac{3 \div 3}{5} + \frac{10 \div 5}{7 \div 7} \times \frac{7 \div 7}{5 \div 5} ) \div (2 - \frac{1}{2} \times \frac{3}{4} ) = ( \frac{1}{5} + \frac{2}{1} ) \div ( \frac{2}{1} - \frac{3}{8} ) = ( \frac{1 + 10}{5} ) \div ( \frac{16 - 3}{8} ) = \frac{11}{5} \div \frac{13}{8} = \frac{11}{5} \times \frac{8}{13} = \frac{88}{65}$
