Question

решите уравнение 3целых3/4х×(1/3+0,4)=1,1

Answer 1

$3 \frac{3}{4} x( \frac{1}{3} + \frac{2}{5} ) = 1 \frac{1}{10} \\ \frac{15}{4} x( \frac{5}{15} + \frac{6}{15} ) = \frac{11}{10} \\ \frac{15}{4} x \times \frac{11}{15} = \frac{11}{10} \\ \frac{11}{4} x = \frac{11}{10} \\ x = \frac{11}{10} \div \frac{11}{4} \\ x = \frac{11}{10} \times \frac{4}{11} \\ x = \frac{4}{10} \\ x = 0.4$
