Question

Put these lengths in order of size starting with the smallest.

54 mm
4.5 cm
0.04 m
51 mm

Answer 1

0.04m, 4.5cm, 51mm, and 55mm

Explanation:

Let's put all measurements into mm because we already have two there.

4.5cm * 10mm/cm = 45mm

0.04m * 1000mm/m = 40mm

40<45<51<55

So the order is 40mm, 45mm, 51mm, 55mm

Convert the two measurements we changes back to their regular form and:

0.04m, 4.5cm, 51mm, and 55mm
