Question

393 Найдите 1/19 часть разности чисел 7 7/9 и 4 11/18​

Answer 1

Ответ: 1/6

$\frac{1}{19} (7 \frac{7}{9} - 4 \frac{11}{18} ) = \frac{1}{19} (7 \frac{14}{18} - 4 \frac{11}{18} ) = \frac{1}{19} \times 3 \frac{3}{18} = \frac{1}{19} \times \frac{57}{18} = \frac{1 \times 57}{19 \times 18} = \frac{3}{18} = \frac{1}{6}$
