Question 55

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

$$P = 18 \times 9 \div 6 + 5 \times 15 \div 25$$

$$P=18\times\frac{9}{6}+5\times\frac{15}{25}$$

$$P=3\times9+\frac{75}{25}$$
$$P=27+3$$
P = 30

$$Q = 15 \div 5 \times 5 - 25 \div 5$$

$$Q=\frac{15}{5}\times5-\frac{25}{5}$$

$$Q=15-5$$

Q = 10


value of $$(P \div Q)$$ = $$\frac{30}{10}$$

= 3
