61. Decimal fractions may be written in two ways; either as other fractions, the denominator being expressed, or in decimal notation, the denominator being omitted. Thus,

The name of the first order at the right of units is tenths;

of the second, hundredths; of the third, thousandths.

62. The unit is the standard by which we compare all numbers. Therefore, to determine the order of units at a glance, a point is placed on the right of the order of units, and before the order of tenths.

It is written thus, (.), and is called the decimal point. Its only purpose is to determine the place of the order of units, and it must never be omitted.

Thus, in the number 62.55, the point shows the order of units, 2; and as we read sixty-two units, so we read fifty-five hundredths, giving to it the name of the lowest order.

63. When an integer and decimal are written together, the expression is a mixed number (52, 4).

Mixed numbers involving decimals are read in the same manner as mixed numbers involving common fractions.

Thus, .07 is read seven hundredths, .58 is read fifty-eight hundredths, 25.34 is read, twenty-five and thirty-four hundredths.

64. The relation of decimals and integers is clearly shown in the following Table:

Read as follows, always using the word "and" between the integer and decimal:

425 and 37 hundredths. 1046 and 65 thousandths. 32400 and 456 thousandths.

87 and 75 ten-thousandths. 4328 and 169 thousandths.
