When a millimeter is less than one, a “0” is shown preceding the decimal point.  Correct0.08 mm  Incorrect.08 mm Copyright © Texas Education Agency, All rights reserved.

A decimal point and a zero are not shown when the millimeter dimension is a whole number.  Correct8 mm  Incorrect8.0 mm Copyright © Texas Education Agency, All rights reserved.

A millimeter dimension with a whole number and a decimal is not shown with a zero following the decimal fraction.  Correct2.2 mm  Incorrect2.20 mm Copyright © Texas Education Agency, All rights reserved.

A metric dimension is given as a decimal fraction rather than a common fraction.  Correct.25 mm  Incorrect¼ mm Copyright © Texas Education Agency, All rights reserved.
