Question

A fossil is 254 millimeters long. How many meters long is the fossil? Enter your answer, as a decimal, in the box.

Answer 1

1mm = 0.001 meter

254 x 0.001 = 0.254 meters long

Answer 2

1000milimeter=1meter
divide both sides by 1000
1mm=1/1000m
times both sides by 254
254mm=254/1000m
254mm=25.4/100m
254mm=2.54/10m
254mm=0.254/1m
254mm=0.254m

it is 0.254 meters
