Question

qual o resultado desta expressão de fração
5/2 + 11/4 : (7/3 x 6/5 - 9/10)

Answer 1

Olá

$\LARGE{} \frac{5}{2} + \frac{11}{4} \div ( \frac{7}{3} \times \frac{6}{5} - \frac{9}{10} ) \\ \\ \LARGE{} \frac{5}{2} + \frac{11}{4} \div ( \frac{7}{\cancel{3}} \times \frac{\cancel{6}}{5} - \frac{9}{10} ) \\ \\ \LARGE{} \frac{5}{2} + \frac{11}{4} \div (7 \times \frac{2}{5} - \frac{9}{10} ) \\ \\ \LARGE{} \frac{5}{2} + \frac{11}{4} \div ( \frac{14}{5} - \frac{9}{10} ) \\ \\ \LARGE{} \frac{5}{2} + \frac{11}{4} \div \frac{19}{10} \\ \\ \LARGE{} \frac{5}{2} + \frac{11}{4} \times \frac{10}{19} \\ \\ \LARGE{} \frac{5}{2} + \frac{11}{\cancel{4}} \div \frac{\cancel{10}}{19} \\ \\\LARGE{} \frac{5}{2} + \frac{11}{2} \times \frac{5}{19} \\ \\ \LARGE{} \frac{5}{2} + \frac{55}{38} \\ \\ \LARGE{}\LARGE\boxed{ \frac{75}{19} }$
