Question

Tom was using wire of the following thicknesses .33 mm, .275 mm, .25 mm, and .3 mm for some electrical work. Order the wire from thickest to thinnest.

Answer 1

0.33mm, 0.3mm, 0.275mm, 0.25mm

Answer 2

Compare the tenths digit of all numbers:

.33
.275
.25
.3

The lower tenths digits will go on the bottom, and the higher tenths digits will go on the top:

.33
.3
.275
.25

Compare the hundredths digit of all numbers:

.33
.3

3 > 0

.275
.25

7 > 5

From thickest to thinnest, the order is .33 mm, .3 mm, .275 mm, and .25 mm.
