Question

(1-4/9):(1/3-1/4).Помогите пожалуйста. Зарание спасибо!)

Answer 1

$1 - \frac{4}{9} = \frac{9}{9} - \frac{4}{9} = \frac{5}{9}$
$\frac{1}{3} - \frac{1}{4} = \frac{4}{12} - \frac{3}{12} = \frac{1}{12}$
$\frac{5}{9} \div \frac{1}{12} = \frac{5}{9} \times \frac{12}{1} = \frac{5 \times 4}{3} \\ = \frac{20}{3} = 6 \frac{2}{3}$

Answer 2

1) 1 - 4/9 = 9/9 - 4/9 = 5/9
2) 1/3 - 1/4 = 4-3/12 = 1/12
3) 5/9 : 1/12 = 5/9 * 12/1 = 5*4/3 = 20/3 = 6 2/3
Ответ: 6 целых 2/3.
