With fractions below 1, we use of before nouns. （１以下の数字は前）

‘Half’ is not always followed by of.

‘Of’ is also possible with decimals below 1.

However, decimals below 1 are often followed directly by plural nouns.

Fractions and decimals over 1 are normally followed by plural nouns.

Note also the structure ‘a … and a half’.

Singular verbs are normally used after fractions, decimals, and other expressions referring to amounts and measurements.

But plural verbs are used when we are talking about numbers of people or things, even after a singular fraction.

When you use these phrases before plural nouns, both singular and plural verbs are possible.

We say each figure separately, pausing after groups of three or four (not two).

0 is often called oh (like the letter O).
