Answer:
Correct conversions:
1.7 cm = 17 mm
345 m = 0.345 km
1.25 km = 1,250 m
Step-by-step explanation:
A)4.7 m = 47,000 mm
1 m = 1000 mm
4.7 m = [tex]4.7 \times 1000= 4700 mm[/tex]
So, the given conversion is incorrect
B)1.7 cm = 17 mm
1 cm = 10 mm
So, 1.7 cm = [tex]1.7 \times 10 = 17 mm[/tex]
So, the given conversion is correct
C)343 m = 34.3 cm
1 m = 100 cm
343 m = 34300 cm
So, the given conversion is incorrect
D)345 m = 0.345 km
1 km = 1000 m
0.345 km = [tex]0.345 \times 1000 = 345 m[/tex]
So,the given conversion is correct
E)1.25 km = 1,250 m
1 km = 1000 m
1.25 km = [tex]1.25 \times 1000 = 1250 m[/tex]
So,the given conversion is correct
