Answer 2

Question :-

• find ratio of following :-

Solution :-

We know one rupee = 100 paise

(a) ₹ 5 to 50 paise

Converting into same units, we have :-

₹ 5 = 5 × 100 = 500 paise

∴ ₹ 5 : 50 paise

= 500 paise : 50 paise

= 10 : 1

So, required ratio is 10 : 1

_________

We know 1 kg = 1000 g

(b) 15 kg to 210 g

Converting same units, we have

15 kg = 15 × 1000

= 15000 g

∴ 15 kg : 210 g

= 15000 g : 210 g

= 1500 : 21

= 500 : 7

So, the required ratio is 500 : 7

_________

We know cm 1 m = 100 cm

(c) 9 m to 27 cm

Converting into same units, we have

9 m = 9 × 100 = 900 cm

∴ 9m: 27 cm

= 900 cm : 27 cm

= 100 : 3

So, the required ratio is 100 : 3.

_________

We know 1 day = 24 hours

(d) 30 days to 36 hours

Converting into same units, we have

30 days = 30 × 24 hours

= 720 Hours

∴ 30 days : 36 hours

= 720 hours : 36 hours

= 20:1

So, the required ratio is 20 : 1.
