Question 1.
235 cm = _____________ m
235 cm = 2.35 m.

Explanation:
235 cm = ?? m.
Conversion:
1 m = 100 cm.
235 cm = 235 ÷ 100
= 2.35 m.

Question 2.
4235 mm = _____________ m
4235 mm = 4.235 m.

Explanation:
4235 mm = ?? m.
Conversion:
1 m = 1,000 mm.
4235 mm = 4235 ÷ 1,000
= 4.235 m.

Question 3.
5.7 km = _____________ cm
5.7 km = 570,000 cm.

Explanation:
5.7 km = ?? cm.
Conversion:
1 km = 100,000 cm.
5.7 km = 5.7 × 100,000
= 570,000 cm.

Question 4.
625 km = _____________ mm
625 km = 62,50,00,000 mm.

Explanation:
625 km = ?? mm.
Conversion:
1 km = 10,00,000 mm.
625 km =625 × 10,00,000
= 62,50,00,000 mm.

Question 5.
235 cm + 300 mm = _____________ m
235 cm + 300 mm = 2.65 m.

Explanation:
235 cm + 300 mm = ?? m.
Conversion:
1 m = 100 cm.
1 m = 1000 mm.
235 cm + 300 mm = (235 ÷ 100) + (300 ÷ 1000)
= 2.35 + 0.3
= 2.65 m.

Question 6.
1.6 km = _____________ cm
1.6 km = 160,000 cm.

Explanation:
1.6 km = ?? cm.
Conversion:
1 km = 100,000 cm
1.6 km = 1.6 × 100,000
= 160,000 cm.

Question 7.
5 cm + 5 mm = _____________ m
5 cm + 5 mm = 5.005 m.

Explanation:
5 cm + 5 mm = ?? m.
Conversion:
1 m = 100 cm.
1 m = 1000 mm.
5 cm + 5 mm = (500 ÷ 100) + (5 ÷ 1000)
= 5 + 0.005
= 5.005 m.

Question 8.
3.87 m = _____________ mm
3.87 m = 3870 mm.

Explanation:
3.87 m = ?? mm.
Conversion:
1 m = 1000 mm.
3.87 m = 3.87 × 1000
= 3870 mm.

Question 9.
5 km + 50 m = _____________ m
5 km + 50 m = 5050 m.

Explanation:
5 km + 50 m = ?? m.
Conversion:
1 km = 1000 m.
5 km + 50 m = (5 × 1000) + 50
= 5000 + 50
= 5050 m.

Question 10.
200 km + 200 m = _____________ cm
200 km + 200 m = 2,00,20,000 cm.

Explanation:
200 km + 200 m = ?? cm.
Conversion:
1 km = 100,000 cm.
1 m = 100 cm.
200 km + 200 m = (200 × 100,000) + (200 × 100)
= 2,00,00,000 + 20,000
= 2,00,20,000 cm.

Question 11.
400 cm = _____________ km
400 cm = 0.004 km.

Explanation:
400 cm = ?? km.
Conversion:
1 km = 100,000 cm.
400 cm = 400 ÷ 100,000
= 0.004 km.

Question 12.
25 m + 10 cm = _____________ cm
25 m + 10 cm = 2,510 cm.

Explanation:
25 m + 10 cm = ?? cm.
Conversion:
1 m = 100 cm.
25 m + 10 cm = (25 × 100) + 10
= 2,500 + 10
= 2,510 cm.

Question 13.
45 m + .25 m = _____________ mm
45 m + .25 m = 45,250 mm.

Explanation:
45 m + .25 m = ?? mm.
Conversion:
1 m = 1,000 mm.
45 m + .25 m = (45 × 1,000) + (0.25 × 1,000)
= 45,000 + 250
= 45,250 mm.
