Σελίδα 89 - Thus ,4-,, -fis^, -p^fa, are decimal fractions, and are usuaiiy written in this manner : -5, -25, -325, the numerators being omitted ; but a point is placed on the left hand to distinguish them from integers. In reading them the first is called 5-tenths, the second 25-hundredths, and the third 325-thousandths. When there are not so many figures in the numerator as there are cyphers in the denominator, as many cyphers as are necessary must be prefixed : thus y^—03 and ^=-003.
