DECIMAL FRACTIONS.

A DECIMAL FRACTION is that, whose denominator is an unit, with as many cyphers annexed to it as the numerator has places, and is usually expressed by writing the numerator only, with a point before it, called the separatrix ; thus to, *, are decimal fractions, and are expressed by ,5 ,25 ,125 respectively.

The figures to the left hand of the feparatrix are whole numbers ; thus 4,5 yards is 4 yards and 5 tenths or one half of another yard.

Cyphers placed to the right hand of decimals, make no alteration in their value; for ,5 ,50 ,500 &c. are decimals of the same value, being each equal to į ; but when placed to the left hand, the value of the fraction is decreased in a tenfold proportion ; thus 5,05,005 &c. are 5 tenth parts, 5 hundredth parts, 5 thousandth parts, respectively.

But the different value of figures will appear plainer by the fol. lowing

TABLE.
Integers.

Decimals.

ao o millions.

no tens of millions.
OOOOoo tens.
NOOo o tens of thousands.

Nooo hundreds of thousands.
NOOOOoo hundreds.

00009 tenths.
OOOOoo hundredths.
NOOOoo thousandths.
NOOo o ten thousandths,
at Ooo hundred thousandths.
do o millionths.
No ten millionths.

n hundred millionths.

From this table it appears, that as whole numbers increase in a tenfold proportion from units to the left hand, fo decimals decrease in the same proportion to the right,--and that in decimals, as in whole numbers, the place of a figure determines its relative value.
