Question

Find the ratio of: (a) ₹ 5 to 50 paise
(b) 15 kg to 210 g
(c) 9 m to 27 cm
(d) 30 days to 36 hours​

Answer 1

Answer:

(a) 1:10

(b) 3:45

(c) 1:3

(d) 5:6

Answer 2

(b) 15 kg to 210 g

Converting the given quantities into same units, we have

15 kg = 15 × 1000

= 15000 g [∵ 1 kg = 1000 g]

∴ 15 kg : 210 g = 15000 g : 210 g

= 1500 : 21

= 500 : 7

So, the required ratio is 500 : 7.

(c) 9 m to 27 cm

Converting the given quantities into same units, we have

9 m = 9 × 100 = 900 cm

∴ 9m: 27 cm = 900 cm : 27 cm [∵ 1 m = 100 cm]

= 100 : 3

So, the required ratio is 100 : 3.

(d) 30 days to 36 hours

Converting the given quantities into same units, we have

30 days = 30 × 24 hours [ ∵ 1 day = 24 hours]

= 720 hours

∴ 30 days : 36 hours

= 720 hours : 36 hours = 20:1

So, the required ratio is 20 : 1.
