Cardinal numerals.
Cardinal numerals indicate exact number, they are used in counting.
Such cardinal numerals as hundred, thousand, million may be used with articles (a hundred, a thousand, a million), they may be substantivized and used in the plural (hundreds, thousands, millions). When used after other numerals they do not take -s (two hundred times, thirty thousand years, etc.). The word million may be used with or without -s (two million, two millions). When the word million is followed by some other cardinal numeral only the first variant is possible: two million five hundred inhabitants.
Ordinal numerals.
Ordinal numerals show the order of persons and things in a series.
With the exception of the first three (first, second, third) the ordinal numerals are formed from cardinal numerals by means of the suffix -th.
In ordinal groups only the last member of the group takes the ordinal form: (the) sixty-fifth, (the) twenty-third. Ordinal numerals are generally used with the definite article: (the first, the fifth, the tenth, etc.).
In fractional numbers the numerator is a cardinal and the denominator is a substantivized ordinal: two-thirds, three-sixths.
Decimal fractions are read in the following way: 7.58 seven point (decimal) five eight.
: . . 1 , . 73 74, . 87.
Theme II.3. Exercises.
Ex. 1. Write in words the following cardinal numbers:
3, 9, 11, 12, 14, 15, 19, 33, 44, 60, 99, 100.
Ordinal numbers:
1st, 3rd, 5th, 9th, 19th, 2nd, 4th, 8th, 12th, 20th.
Ex. 2. Write in words the following numerals:
134, 298, 355, 948, 3526, 9011, 193, 561, 7 506 017, 35 616 234, 104, 151, 175, 189, 1012, 1017, 1038, 2568, 4083, 5993, 6410, 10 784, 257 629, 841 403, 2 184 001.
Ex. 3. Write in words:
Model:
13 +45 = 58 (Thirteen plus forty-five is fifty-eight).
50 -31 = 19 (Fifty minus thirty-one is nineteen).
15 x 2 = 30 (Fifteen multiplied by two is thirty).
30: 2 = 15(Thirty divided by two is fifteen).
46 + 18 =64 4 + 40 = 44 30: 5 = 6 10: 5 =2
15 8 = 7 10 + 8 = 18 5x5 =25 6 x 8 = 48
80 30 = 50 79 50 = 29 9x9 = 81 6 x 6 = 36
9 + 11 = 20 99 + 1 = 100 10: 2 = 5 27: 3 = 9
