Step-by-step explanation:
let the number be x
[tex]1 \div 3 \: of \: x \\ x \div 3 = 1 \div 2 \: of \: x - 6 \\ x \div 3 = x \div 2 - 6 \\ multiply \: both \: sides \: by \: the \: lcm \: 6 \\ x \div 3 \times 6 = x \div 2 \times 6 - 6 \times 6 \\ x \times 2 = x \times 3 - 36 \\ 2x = 3x - 36 \\ 2x - 3x = - 36 \\ - x = - 36 \\ divide \: both \: sides \: by \: - 1 \\ - x \div - 1 = - 36 \div - 1 \\ x = 36[/tex]
