Question

List these in increasing order of length 7cm, 18mm, 1m, 3dm

Answer 1

Answer:

18 mm < 7 cm < 3 dm < 1m

Step-by-step explanation:

It has been given the lengths

7 cm, 18 mm, 1 m, 3 dm

Let us convert all these lengths in centimeter.

1 m = 100 cm

1 mm = 0.1 cm

1 dm = 10 cm

Thus, we have

18 mm = 1.8 cm

3 dm = 30 cm

1 m = 100 cm

Thus, we can arrange this in increasing order as

1.8 < 7 < 30 < 100

Hence, we have

18 mm < 7 cm < 3 dm < 1m

Answer 2

1m, 3dm because it equals .3m, 7cm because it equals .07, 18mm because it equals .0018m
