Question

There are 10 mm in one cm and 100 cm in 1m. an adult alligator is about 4,000 mm long and an adult crocodile is abt 6m long

Which is longer?


HELP PLEASE

Answer 1

Answer: crocodile is longer
To get from mm to m, you would divide by 1000. 4000/1000 is 4, meaning the alligator is 4m and the croc is 6m (therefore longer)

Answer 2

the crocodile is longer

Explanation:

To compare the lengths directly, we need to convert them to the same units. It is convenient to express the length of the alligator in meters.

__

The length of the alligator is ...

4000 mm = (4000 mm)×(1 cm)/(10 mm)×(1 m)/(100 cm)

= 4000/(10×100) m = 4 m . . . . length of an alligator

The crocodile is 6 m long; the alligator is 4 m long, so the crocodile is longer.
