Question

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

Answer 1

изи будет x равно 2/3

Answer 2

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