Answer

Order each set of measures from greatest to least: 1.2 cm, 0.6 in., 0.031 m, 0.1 ft

We need to convert all units into meters( m ) so we can compare:

0.1 ft is equal to: 0.1ft x 0.3 = 0.030 m

1.2 cm is equal to: 1.2cm x 1/100 = 1.2 x 0.01 = 0.012 m

0.6 in is equal to: 0.6in x 0.025 = 0.015 m

0.031m > 0.030m > 0.015m > 0.012m

0.031m > 0.1ft > 0.6in > 1.2cm
