(1) 4p²q : 10pq²

tiny-mole [99]

Answer: (1) 2p: 5q.

(2) 3:10.

(3) 5:6.

Step-by-step explanation:

To find : Ratio

(1) 4p²q : 10pq²

$=\dfrac{4p^2q}{10pq^2}\\\\=\dfrac{2p^{2-1}}{5q^{2-1}}\\\\=\dfrac{2p}{5q}$

i.e. Simplified ratio of 4p²q : 10pq² is 2p: 5q.

(2) 9 months : 2½ years

1 year = 12 months

$2\dfrac{1}{2}\text{years}=\dfrac{5}{2}\text{years}\\\\=\dfrac{5}{2}\times12=30\text{ months}$

Now, 9 months : 2½ years = $\dfrac{9\text{ months}}{30\text{ months}}=\dfrac{3}{10}$

Hence, Simplified ratio of 9 months : 2½ years is 3:10.

(3) 5 m : 600 cm

1 m = 100 cm

So, 5m = 500 cm

Now, 5 m : 600 cm = $\dfrac{500\ cm}{600\ cm}=\dfrac{5}{6}$

Hence, Simplified ratio of 5 m : 600 cm is 5:6.
