Answer 1

Answer:

The correct ones:

1.7 cm = 17 mm

345 meters = 0.345 kilometer

1.25 kilometers = 1,250 meters

Step-by-step explanation:

There are 1000 millimeters = 1 meter

so  

4.7 m = 4.7 meters  * (1000 millimeters/1 meter) = 4,700 mm  not 47,000

343 m * 100 cm /1 m =   34,300 cm  not 34.3 cm

-----------------------------

1.7 cm *  10 mm/1cm = 17 mm

345 m  *  (1 km / 1000 m) =  0.345 km

1.25 km  *  1000 m/ 1 km  =  1, 250 meters
