$P = 18 \times 9 \div 6 + 5 \times 15 ÷ 25$ and $Q = 15 \div 5 \times 5 - 25 \div 5$, what is the value of (P ÷ Q) ?

Given: P = 18 × 9 ÷ 6 + 5 × 15 ÷ 25 Q = 15 ÷ 5 × 5 - 25 ÷ 5 So, P = 18 × 9 ÷ 6 + 5 × 15 ÷ 25 = 18 x \(\frac{9}{6}\) + 5 x \(\frac{15}{25}\) = 19 x 3 + 3 = 30 Q = 15 ÷ 5 x 5 - 25 ÷ 5 = \(\frac{15}{5}\) x 5 - \(\frac{25}{5}\) = 15 - 5 = 10 (P ÷ Q） = \(\frac{30}{10}\) = 03
