All you need to to is remember 1Km = 1000m and 1m = 1000mm
so mm expressed as meters is 50 divided by 1000 = 0.05m
and 0.05m in Km we have to devide by 1000 again so that's = 0.00005Km
so 50mm = 0.00005Km
1 km = 1000 meters = 106 millimeter
Answer = 50 km = 50 x 106 mm or 50 million millimeter
1 km equals 100,000 mm
0.045 km
120,000,000 mm = 120km
1000 mm = 1 m 1000 m = 1 km ⇒ 1000 x 1000 mm = 1000000 mm = 1 km ⇒ 50 mm = 50 ÷ 1000000 km = 0.00005 km
1m = 1/1000 km 0.03 m = 0.03/1000 =0.00003 km
1 km equals 100,000 mm
8490 mm = 0.00849 km
0.045 km
120,000,000 mm = 120km
45000 mm = 0.045 km
0.05km equals 50,000mm (km x 1,000,000 = mm)
the answer is 5
its 823000000mm
Convert the km to mm, then the units can be removed and the ratio found: 1 m = 1,000 mm 1 km = 1,000 m = 1,000 x 1,000 mm = 1,000,000 mm ⇒ 1 mm : 50 km → 1 mm : 50 x 1,000,000 mm → 1 mm : 50,000,000 mm → 1 : 50,000,000
1000 mm = 1 m 1000 m = 1 km ⇒ 1000 x 1000 mm = 1000000 mm = 1 km ⇒ 50 mm = 50 ÷ 1000000 km = 0.00005 km
By unit of length and distance and conversion ,we can say that 1 km =1000000 mm 5.2 mm =0.0000052 km
1m = 1/1000 km 0.03 m = 0.03/1000 =0.00003 km
