Fundamental Questions & Answers about Numerals in English
Q1: What are the two main types of numerals in English?
A1: The two main types of numerals in English are cardinals (one, two, three, etc.) which indicate quantity, and ordinals (first, second, third, etc.) which indicate position or order in a sequence.
Q2: How do we form cardinal numbers from 1 to 10 in English?
A2: The cardinal numbers from 1 to 10 in English are:
- One
- Two
- Three
- Four
- Five
- Six
- Seven
- Eight
- Nine
- Ten
Q3: How are ordinal numbers formed in English?
A3: Most ordinal numbers in English are formed by adding the suffix "-th" to the corresponding cardinal number, with exceptions for "first" (1st), "second" (2nd), and "third" (3rd). Other exceptions include "fifth" (5th) and "ninth" (9th) which change the spelling, and "twelfth" (12th) which is abbreviated.
Q4: What is the rule for writing numbers in digit or word form in English?
A4: In English, the general rule is to write numbers from one to ten in word form, and numbers larger than 11 in digit form. However, in formal contexts, larger numbers can also be written in word form.
Q5: How do we transform an ordinal number into a cardinal number?
A5: To transform an ordinal number into a cardinal number, we remove the ordinal suffix (-st, -nd, -rd, -th) and refer to the basic form of the number. For example, "first" becomes "one", "second" becomes "two", and "twenty-first" becomes "twenty-one".
Q6: Are there exceptions in forming ordinals for compound numbers?
A6: Yes, for compound numbers, only the last number takes the ordinal form. For example, "twenty-first" for 21st, "thirty-second" for 32nd.
Q7: How are decimal numbers said in English?
A7: In English, decimal numbers are said using the word "point" to indicate the decimal separator. Then each digit is said individually. For example, "3.14" is said as "three point one four".
Q8: How are fractions expressed in English?
A8: Fractions are expressed in English using cardinal numbers for the numerator and ordinals for the denominator, with some exceptions like "half" (1/2) and "quarter" (1/4). For example, "3/4" is "three quarters".
Q9: Are there differences between British and American English in the use of numerals?
A9: Yes, there are some differences. For example, the numeral "0" is commonly called "zero" in American English and "nought" or "oh" in British English. There are also variations in how dates and large numbers are enunciated.
Q10: How do we read dates in English?
A10: Dates can be read differently depending on whether it is American or British English. In American English, the month is read first, then the day and year (MM/DD/YYYY), for example, "July 4th, 1776". In British English, the day is read first, then the month and year (DD/MM/YYYY), for example, "4th July 1776".

Explanation: Remember that "zero" is the base for counting and may have different names depending on the English variant.
Q2: How do you say "two and a half" in English?
A2: "Two and a half" is said in English as "two and a half".
Explanation: The expression "and a half" is commonly used to indicate half after a whole number.

A3: The ordinal number for "fourth" in English is "fourth" and is written as 4th.
Explanation: The general rule is to add "-th" at the end of the cardinal number, but always check for exceptions.
Intermediate Q&A
Q4: How do we read the number "101" in English?
A4: The number "101" is read in English as "one hundred and one" in British English or "one hundred one" in American English.
Explanation: Note the difference in including the conjunction "and" after hundreds in British English.
Q5: How do you say "2/3" in English?
A5: The fraction "2/3" is said in English as "two thirds".
Explanation: For fractions where the numerator is greater than one and the denominator is not a power of ten, the denominator is expressed in the plural.
Q6: What are the rules for writing numbers as words in formal contexts?
A6: In formal contexts, numbers up to "one hundred" are often written in word form; larger numbers can be written numerically unless they start a sentence.
Explanation: Writing numbers as words in formal contexts helps avoid ambiguity and makes the text more formal.
Advanced Q&A
Q7: How do we express "1,000,000" in words in British and American English?
A7: "1,000,000" is expressed in words as "one million" in both British and American English.
Explanation: Despite some differences between British and American English in terms of numerals, the expression of very large numbers tends to be the same.
Q8: How do you read the number "0.304" in English?
A8: The number "0.304" is read in English as "zero point three oh four" in American English or "nought point three oh four" in British English.
Explanation: When reading decimal numbers, the decimal part is read digit by digit after the word "point".
Q9: What is the ordinal form of compound numbers like "112"?
A9: The number "112" in ordinal form is "one hundred and twelfth" in British English and "one hundred twelfth" in American English.
Explanation: In compound numbers, only the last element of the number takes the ordinal form.
Q10: Is there a rule for pronouncing large numbers like "14,000" in English?
A10: Yes, "14,000" is pronounced as "fourteen thousand". "And" is not said before "thousand" in American English, while it can be used in British English for exact numbers.
Explanation: Pronouncing large numbers in English involves dividing the number into groups of three digits, starting from the right, and reading each group according to its position (thousands, millions, etc.).
Practical Q&A on Numerals in English
Applied Q&A
Q1: If you are planning a trip to an English-speaking country and need to book a hotel for the "twenty-second day" of a month, how should you express that date in English when making the reservation?
A1: You should express that date as "the twenty-second" when making the reservation. If you needed to provide the full date, you would say, for example, "I would like to book a room for the twenty-second of July" in British English, or "I would like to book a room for July twenty-second" in American English.
Explanation: Here, it is crucial to use the ordinal form of the number to indicate the day of the month. Remember that the date order changes depending on whether you are using American or British English.
Experimental Q&A
Q1: How would you design an educational game to help students practice converting ordinal numbers to cardinals in English?
A1: One possible educational game would involve cards with ordinal numbers on one side and cardinals on the other. Students could play in pairs or groups, with one student drawing a card and reading the ordinal number to the other, who must say the cardinal equivalent. We could add a timer to introduce a challenge element, encouraging students to respond as quickly as possible. Points would be awarded for correct answers and speed, with the aim of making the learning process both interactive and fun.
Explanation: This game helps reinforce the skill of quickly recognizing and converting between ordinal and cardinal numbers, a practical skill in real-life situations such as scheduling meetings or events.
