- Notice that the first row of fractions is exactly the same numbers as
- the Whole Numbers.ïRow two is all of the fractions with "2" in the
- denominator (bottom).ïRow three is all of the fractions with "3" in the
- denominator and so on.ïThe numbers in the first column are actually
- just different representations of the number Zero.ïThe three dots mean
- that the pattern continues on forever.
-
- Find the diagonal of fractions consisting of the numbers 1/1, 2/2, 3/3,
- 4/4, ...ïThese fractions are just different representations of "1".ïNo
- tice that every fraction beneath this diagonal is a Proper Fraction (the
- top is smaller than the bottom), and all of the fractions above this
- diagonal are improper fractions (the top is larger than the bottom).
-
- All of the Proper Fractions can be located on the number line between "0
- " and "1".ïTo locate the Proper Fraction,ï3/4 , on the number line, it
- is necessary to divide the segment from "0" to "1" into four equal parts.
- The fraction, 3/4, is then located at the third division mark.

- êë The Improper Fractionï5/4ïis located at "C".
- éS To locate the Improper Fraction,ï5/4 , on the number line,
- it is first necessary to write the Improper Fraction as a mixed number.
- You can do this by dividing "4" into "5" and getting 1 with remainder 1.
- This is written as "1 1/4".è 5êï1
- #êêêêè─è=è1 ─
- êêêêè4êï4
-
- Then to locate "1 1/4" on the number line, you should first locate the
- whole number "1" and then divide the interval from "1" to "2" into
- #four equal parts.ï──┼───────────────┼───┼───┼───┼───┼─¥
- #êêê0êê 1êê 2êêï═
-
- Finally, you should locate the mixed number,ï1 1/4 or its equivalent 4,
- at the first mark past the number "1".

- êêêêè8êè8
- éS To change the mixed number,ï7 5/8 , to Improper Fraction
- form, it is first necessary to multiply "8" times "7".
- êêêê8 ∙ 7è=è56
-
- This product is added to the numerator (top number) of the fractional
- part and placed over the "8".
- êêêë56 + 5êï61

- êêêê 8êë8
