Hint: For the part (i) of the question use the relation 0.01 Rs. = 1 paise to convert both the quantities into decimals and perform the subtraction to get the answer. For parts (ii) and (iii) use the relations 0.01 m = 1 cm and 0.001 km = 1 m respectively while for the part (iv) use the relation 0.001 kg = 1 g to convert into decimals.

Complete step by step answer:

(i) Here we have to subtract 33 rupees 99 paise from 66 rupees 1 paisa but first we need to convert both the units into decimals. Now, we know that 1 Rs. = 100 paise, so 1 paise = 0.01 rupees, therefore we can write: -

⇒ 33 rupees 99 paise = 33 rupees + 0.99 rupees = 33.99 rupees

⇒ 66 rupees 1 paise = 66 rupees + 0.01 rupees = 66.01 rupees

Subtracting 33.99 rupees from 66.01 rupees we get,

∴ 66.01 rupees – 33.99 rupees = 32.02 rupees

(ii) Here we have to subtract 101 m 50 cm from 102 m 5 cm but first we need to convert both the units into decimals. Now, we know that 1 m = 100 cm, so 1 cm= 0.01 m, therefore we can write: -

⇒ 101 m 50 cm = 101 m + 0.50 m = 101.50 m

⇒ 102 m 5 cm = 102 m + 0.05 cm = 102.05 m

Subtracting 101.50 m from 102.05 m we get,

∴ 102.05 m – 101.50 m = 0.55 m

(iii) Here we have to subtract 6 km 10 m from 16 km 100 m but first we need to convert both the units into decimals. Now, we know that 1 km = 1000 m, so 1 m= 0.001 km, therefore we can write: -

⇒ 6 km 10 m = 6 km + 0.010 km = 6.010 km

⇒ 16 km 100 m = 16 km + 0.100 km = 16.100 km

Subtracting 6.010 km from 16.100 km we get,

∴ 16.100 km – 6.010 km = 10.090 km

(iv) Here we have to subtract 15 kg 656 g from 15 kg 744 g but first we need to convert both the units into decimals. Now, we know that 1 kg = 1000 g, so 1 g = 0.001 kg, therefore we can write: -

⇒ 15 kg 656 g = 6 kg + 0.656 kg = 15.656 kg

⇒ 15 kg 744 g = 15 kg + 0.744 kg = 15.744 kg

Subtracting 15.656 kg from 15.744 kg we get,

∴ 15.744 kg – 15.656 kg = 0.088 kg
