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

Answer 1

Answer:

a. 10 : 1

a. 10 : 1b. 500 : 7

c. 100 : 3

d. 20 : 1

Step-by-step explanation:

a. ₹5 = 5×100 paise (₹1 = 100 paise)

a. ₹5 = 5×100 paise (₹1 = 100 paise) ₹5 = 500 paise

a. ₹5 = 5×100 paise (₹1 = 100 paise) ₹5 = 500 paise Ratio = ₹5/50paise

a. ₹5 = 5×100 paise (₹1 = 100 paise) ₹5 = 500 paise Ratio = ₹5/50paise = 500/50

a. ₹5 = 5×100 paise (₹1 = 100 paise) ₹5 = 500 paise Ratio = ₹5/50paise = 500/50 = 10/1

a. ₹5 = 5×100 paise (₹1 = 100 paise) ₹5 = 500 paise Ratio = ₹5/50paise = 500/50 = 10/1 = 10 : 1.

b. 15kg = 15×1000g (1kg = 1000g)

15kg = 15×1000g (1kg = 1000g) 15kg = 15000g

15kg = 15×1000g (1kg = 1000g) 15kg = 15000g Ratio = 15kg/210g

= 15000/210

= 15000/210 = 500/7

= 15000/210 = 500/7 = 500 : 7.

c. 9m = 9×100cm (1m = 100cm)

9m = 900cm

Ratio = 9m/27cm

= 900/27

= 100/3

= 100 : 3.

d. 30 days = 30×24 hours (1 day = 24 hours)

) 30 days = 720 hours

Ratio = 30 days/36 hours

= 720/36

= 20/1

= 20 : 1.
