Answers
Hope this will help....
if you are satisfied then please like
Rs 5.25
We know that 100 paisa = 1 rupee.
So, 1 paisa = 1/100 rupee.
Therefore, Rs 5.25 = 5 + 0.25
= 5 + 25100
= Rs 5 and 25 paisa
(ii) 8.354 kg
We know that 1000 g = 1 kg.
So, 1 g = 1/1000 kg.
Therefore, 8.354 = 8+ 0.354
= 8 + 3541000
= 8 kg 354 g
(iii) 3.5 cm
We know that 10 mm = 1 cm.
So, 1 mm = 1/10 cm.
Therefore, 3.5= 3+ 0.5
= 3 + 510
= 3 cm and 5 mm
(iv) 3.05 km
We know that 1000 m = 1 km.
Therefore, 3.05 = 3+ .05
= 3+ 5/100 = 3+ 50/1000 km
= 3 km and 50 m
(v) 7.54 m
We know that 100 cm = 1 m.
Therefore, 7.54 = 7+ 0.54
= 7+ 54/100
= 7 m and 54 cm
(vi) 15.005 kg
We know that 1 kg = 1000 g.
Therefore, 15.005= 15 + 0.005
= 15+ 5/1000
= 15 kg and 5 g
(vii) 12.05 m
We know that 1 m = 100 cm.
Therefore, 12.05 = 12 +.05
= 12 + 5/100
= 12 m and 5 cm
(viii) 0.2 cm
We know that 1 cm = 10 mm.
Therefore, 0.2 = 2/10
= 2 mm
