mathematical concept to be studied along with the other basic operations. Each fraction is introduced through the medium of multiplication. From ‘two red rods equal one pink rod’ he obtains that a red rod is half a pink rod; from ‘two white rods equal one red rod’ it follows that one white rod is half a red rod; or, 2 × 2 = 4, thus 2 = × 4; and 2 × 1 = 2, hence 1 = × 2. Thirds, fourths and fifths are similarly obtained. (Mathematics, Part IV, Book I, exercises 19, 27, 30 and 35.)
