Question

Organize the lengths below from the shortest to the longest. 28 dm 629,000 mm 1.2 km 30,277 cm

Answer 1

Answer:

convert all the measurements to a standard form eg km

1dm = 0.0001km

Therefore 28dm = 0.0028km

1mm = 1x10^-6km

Therefore 629000mm = 0.629km

1cm = 1x10^-5km

Therefore 30277cm = 0.30277km

Therefore organising the shortest to the longest

0.0028km(28dm) < 0.30277km(30277cm) < 0.629km(629000mm) < 1.2km

So,

28dm < 30277cm < 629000mm < 1.2km
