Identify the quantities that are equivalent to 250 meters. ratio conversion table kilometer (km) : meter (m) 1 : 1,000 meter (m) : centimeter (cm) 1 : 100 centimeter (cm) : millimeter (mm) 1 : 10 2.5km 0.250km 2,500cm 25,000cm 250mm choose 2 or 3

1.) Convert all measurements to meters:
2.5km * 1,000 = 2,500m ; .250km * 1,000 = 250m ; 2,500cm / 100  = 25m
25,000cm / 100 = 250m ; 250mm / 1,000 = .25m

2.) Compare the converted measurements. Therefore, the quantities that are equivalent to 250m are:
.250km ; 25,000cm
