Question

16.
х:4=9:12
х:3=2:9
5:3=х:8
1:4=12:х​

Answer 1

Ответ:

$x \div 4 = 9 \div 12 \\ 12x = 9 \times 4 \\ 12x = 36 \\ x = 3$

$x \div 3 = 2 \div 9 \\ 9x = 6 \\ x = \frac{2}{3}$

$5 \div 3 = x \div 8 \\ 3x = 8 \times 5 \\ 3x = 40 \\ x = 13 \frac{1}{3}$

$1 \div 4 = 12 \div x \\ x = 4 \times 12 \\ x = 48$
