Решите уравнения.
4х=2,8
12,5:х=5

8х=0,24
0,75:х=3

10х=0,04
0,01:х=10​

Answer 1

Ответ:

$4x = 2.8 \\ x = 0.7 \\ \\ 12.5 \div x = 5 \\ x = 12.5 \div 5 \\ x = 2.5 \\ \\ 8x = 0.24 \\ x = 0.03 \\ \\ 0.75 \div x = 3 \\ x = 0.75 \div 3 \\ x = 0.25 \\ \\ 10x = 0.04 \\ x = 0.004 \\ \\ 0.01 \div x = 10 \\ x = 0.01 \div 10 \\ x = 0.001$
