СРОЧНО ПЖ Я ДАМ 25 БАЛЛОВ !!!!

Answer 1

Ответ:

$1 \frac{7}{8} \div 8 \frac{1}{3} = x \div \frac{4}{9} \\ x \div \frac{4}{9} = 1 \frac{7}{8} \div 8 \frac{1}{3} \\ x \div \frac{4}{9} = \frac{9}{40} \\ x = \frac{9}{40} \times \frac{4}{9} \\ x = \frac{1}{10} \\ 1 \frac{7}{8} \div 8 \frac{1}{3} = \frac{1}{10} \div \frac{4}{9} \\ \frac{9}{40} = \frac{9}{40}$

Answer 2

Пошаговое объяснение:

1 7/8 : 8 1/3 = x:4/9

8 1/3•x=1 7/8•4/9

25/3•x=15/8•4/9

25/3•x=5/6

x=5/6:25/3

x=5/6•3/25

x=1/10
