Question 3.
Convert into indicated units:
(i) 10 l and 5 ml into ml
(ii) 4 km and 300 m into m
(iii) 300 mg into g
Solution:
(i) 10 l and 5 ml
= 10 × 1000 ml + 5 ml
= 10,000 ml + 5 ml [∴ 1l = 1000 ml]
= 10,005 ml.
∴ 10 l and 5 ml = 10,005 ml.
(ii) 4 km and 300 m into m.
4 km and 300 m
= 4 × 1000 m + 300 m
= 4000 m + 300 m [∴ 1 km = 1000 m]
= 4300 m
∴ 4 km and 300 m = 4300 m
(iii) 300 mg into g.
Question 4.
Convert into higher units:
(i) 13000 mm (km, m, cm)
(ii) 8257 ml (kl, l)
Solution:
(i) 13000 mm (km, m, cm)
(ii) 8257 ml (kl, l)
Question 5.
Convert into lower units:
(i) 15 km (m, cm, mm)
(ii) 12 kg (g, mg)
Solution:
(i) 15 km (m, cm, mm)
15 km = 15 × 1000 m = 15,000 m
15 km = 15 × 1,00,000 cm = 15,00,000 cm
15 km = 15 × 10,00,000 mm = 1,50,00,000 mm.
15 km = 15,000 m = 15,00,000 cm = 1,50,00,000 mm.
(ii) 12 kg (g, mg)
12 kg = 12 × 1000 g= 12,000 g
12 kg = 12 × 10,00,000 mg = 1,20,00,000 mg.
12 kg = 12,000 g = 1,20,00,000 mg.
Question 6.

(i) <
(ii) =
(iii) =
(iv) <
(v) >
Question 7.
Geetha brought 2 l and 250 ml of water in a bottle. Her friend drank 300 ml from it. How much of water is remaining in the bottle?
Solution:
Total Capacity of water = 2 l 250 ml

Water Consumed = 300 ml
Water remaining in the bottle = (2250 – 300) ml
= 1950 ml
= 1 litre 950 ml
Question 8.
Thenmozhi’s height is 1.25 m now. She grows for 5 cm every year. What would be her height after 6 years?

height = 1.25 m
Every year’s growth = 5 cm
Total height in I year = 1,25 m and 5 cm
∴ Height after 6 years = 1.25 m + (5 cm × 6)
= 1.25 m + 30 cm
= 125 cm + 30 cm
= 155 cm
