Пожалуйста помогите

Answer 1

$1)0.21x = 6.3 \\ 0.21x \div 0.21 = 6.3 \div 0.21 \\ x = 30 \\ \\ 4)0.132x = 132 \\ 0.132x \div 0.132 = 132 \div 0.132 \\ x = 100 \\ \\ 7)13.5x = 1.08 \\ 13.5x \div 13.5 = 1.08 \div 13.5 \\ x = 0.08 \\ \\ 10)0.32x = 16.48 \\ 0.32x \div 0.32 = 16.48 \div 0.38 \\ x = 51.5$
