Expression of English scores:

1. Expressed by "radix+ordinal number".

In English, scores are usually expressed by means of cardinal words and ordinal numbers. Where radix represents numerator and ordinal number represents denominator.

For example:

One tenth, one third.

From the above example, we can see that: A can also be used for molecules except one; If the numerator is greater than 1, the denominator should be plural.

However, 1/2 is not (one) second, but (one) half a second.

For example:

Half, 1/2, one third, one quarter

1/4 and 3/4 can be said to be one quarter and three quarters, but they are often expressed as one quarter and three quarters.

It should be noted that when a fraction modifies a noun, if the noun is uncountable, it can only be singular; If it is a countable noun, it can be singular or plural. But if it is the subject in a sentence, whether the predicate verb is singular or plural depends on the noun, that is, it is consistent with the noun modified by the fraction. For example:

There is only one-fifth oxygen in the air. Oxygen only accounts for 1/5 of air.

About two thirds of the students attended the meeting. About two thirds of the students attended the meeting.

Fraction is also a common expression of English numerals. The so-called fraction is actually "integer+fraction", which is expressed by time, but the integer part and the fraction part should be connected by the conjunction and. When nouns are modified by fractions, they are usually plural, but if nouns are placed after integer one or a, they are singular. When "with fraction+noun" is the subject, according to the principle of proximity, the predicate verb should be plural. For example:

You should finish this work in one and a quarter hours. You should finish the work in 1.25 hours.

7. The atom splits after a minute and a quarter. Atoms split in 1.25 minutes.

Second, it is expressed in percentage, etc.

One percent can be said to be one percent, but one percent or one percent is more commonly used, that is, expressed as a percentage. For example:

8. Our bodies are 65% water. Our bodies contain 65% water.

9. Seventy-five percent of the earth's surface is covered by water. 75% of the earth's surface is covered with water.

10. Eighty-five percent of the students in the English department are girls. 85% of the students in the English department are girls.

Third, partial expression

The noun part means "one third of ...". When the molecule is greater than 1, this part is a complex number. Generally speaking, there are three kinds of structures to represent fractions:

(1) One percent of "cardinal word (or one)+ordinal number+part".

(2) "radix+part+median+radix" five+part+median+one thousand.

(3) "radix+part+per+radix"+part+per+million.

Fourthly, it is expressed by "cardinal words+prepositions+cardinal words"

With the help of prepositions, numerals before prepositions are molecules and numerals after prepositions are denominators. For example:

1 1. If asked who discovered America first, 99% of the forgotten people will answer Columbus ... If you ask who discovered America first, 99% will answer Columbus.

Prepositions in this structure mainly include in, out, of and to.

12. This map is drawn at the scale of 1/10000. This map is drawn at a scale of one in ten thousand.
