Answer 2

$\huge\underline\mathcal\blue{Answer:---}$

(i) ₹ 5 to 50 paise

= 500 paise : 50 paise

= 10 : 1 (Dividing by 50)

(iii) 9 m to 27 cm

= 9 × 100 cm : 27 cm

= 100 : 3 (Dividing by 9)

(iv) 15 kg to 210 g

= 15 × 1000 g : 210 g

= 15000 : 210

= 500 : 7 (Dividing by 30)

(v) 25 minutes to 1.5 hours

= 25 minutes to $\frac{3}{2}$× 60

= 25 : 90

= 5 : 18

(vi) 30 days to 36 hours

= 30 × 24 hours to 36 hours

= 720 : 36

= 20 : 1 (Dividing by 36)
