Answer 1

$12 \div 100 \times x = 40000 \\ 3 \div 25 \times x = 40000 \\ x = 40000 \times 25 \div 3 \\ x = 1000000 \div 3 \\ x = 333333.33333333$

Answer 2

$\dfrac{12}{100} \cdot x = 40000 \Big|\cdot \dfrac{100}{12} \\ \\ \dfrac{100}{12} \cdot \dfrac{12}{100} \cdot x = 40000 \cdot \dfrac{100}{12} \\ \\ \Rightarrow \dfrac{100}{100} \cdot x = 333.333,(3)$

$\dfrac{12}{100} \cdot x = 40000 \Big|\cdot \dfrac{1}{6} \\ \\ \dfrac{1}{6} \cdot \dfrac{12}{100} \cdot x = 40000 \cdot \dfrac{1}{6} \\ \\ \Rightarrow \dfrac{2}{100} \cdot x = 6.666,(6)$
