Question

Select all correct conversions. 4.7 m = 47,000 mm, 1.7 cm = 17 mm , 343 m = 34.3 cm, 345 m = 0.345 km , 1.25 km = 1,250 m

Answer 1

Correct conversions:

1.7 cm = 17 mm

345 m = 0.345 km

1.25 km = 1,250 m

Explanation:

A)4.7 m = 47,000 mm

1 m = 1000 mm

4.7 m =
`4.7 * 1000= 4700 mm`

So, the given conversion is incorrect

B)1.7 cm = 17 mm

1 cm = 10 mm

So, 1.7 cm =
`1.7 * 10 = 17 mm`

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 =
`0.345 * 1000 = 345 m`

So,the given conversion is correct

E)1.25 km = 1,250 m

1 km = 1000 m

1.25 km =
`1.25 * 1000 = 1250 m`

So,the given conversion is correct
