    Common fractions or vulga<\/em><\/strong>r: \u00bd, \u00bc, \u00be, 3\/8 and 5\/8 are called fraction. One number over another. Numerator is the term given to the number on the top part of a fraction. De nominator is the term given to the number at the bottom part of a fraction.\n<\/div>\n

  2. Decimal fractions<\/strong>: are simply called decimals example 0.897, 7.864 etc.\n<\/li>\n
  3. Proper fraction<\/strong>: the numerator is less than the denominator. e.g. 2\/5, \u00bc,ect\n<\/li>\n
  4. An improper fraction<\/strong> the numerator is greater than the denominator e.g 8\/3, 12\/5 etc.\n<\/li>\n<\/ol>\n

    CHANGING AN IMPROPER FRACTION TO A MIXED NUMBER

    \nSolution<\/strong>:
    \n = = =

    \nEQUIVALENT FRACTIONS<\/strong>
    \n\t\tFraction that have the same value are said to be equivalent. Example are \u00bd, 2\/4, 3\/6, 4\/8, 5\/10, 6\/12 etc.
    \nExample 1: convert 2\/9 into an equivalent fraction with the denominator 54
    \nSolution:
    \n\"\"\/2\/9 = \/54 (divide the second denominator by the first denominator to obtain the multiplier)
    \n54\/9 =6
    \nTherefore use the 6 to multiply 2\/9= 12\/54
    \n2\/9 =12\/54
    \n\"\"\/\"\"\/Finding the missing part of these fractions: \/10 =12\/= = 20\/50 = \/ 80
    \nSolution
    \nStep 1 Use 20\/50 as your reference fraction because both its numerator and denominator are given. 20\/50 = 2\/5
    \n\"\"\/10\/5 (use the 5 of denominator to get your numerator of \/10) =2
    \nTherefore use 2 to multiple both 2\/5 =4\/10
    \n\"\"\/Step 2 use the 2 to divide the numerator of 12\/ to get 6 and use the 6 to multiply 2\/5 = 12\/30
    \nStep 3: use 5 to divide the denominator of 80 to get 16
    \nTherefore use 16 to multiply 2 \/ 5 = 32 \/80
    \nSo 4\/10 = 12\/30 = 20\/50 =32\/80.
