WEEK 5\u00a0\u00a0\u00a0\u00a0FRACTIONS (CONVERTION FROM PERCENTAGE TO DECIMAL AND DECIMAL TO FRACTION)
\n<\/h5>\n

CONTENT: To convert a fraction into a decimal, first rewrite the numerator as a decimal, then divide it by the denominator.
\nExample 1 (a) change into a terminating decimal number (b) to decimal fraction
\nSolution:<\/p>\n

    \n
  1. Numerator 3 can be written I decimal number as 3.0 or 3.00 0r 3.000\n<\/li>\n<\/ol>\n

    = 0.75 I,e 4 divide 3, then add zero, 4 goes in 30 is ,it remain 2, add 0 to make it 20 and 4 in 20 gives 5
    \nTherefore = 0.75<\/p>\n

      \n
    1. 8 divies 5,it becomes 0,then add zero to make it 50,it gives 6, it remains 2, add zero it becomes 20, 8 divides 20 is 2, it remains 4, add zero to gives 40, 8 in 40 is 5\n<\/li>\n<\/ol>\n

      Therefore = 0.625.
      \nCONVERTING DECIMALS TO FRACTIONS
      \nTo change a decimal into a fraction, count the digits after the decimal, then divide by the appropriate power of 10,i.e 10,100,1000.
      \nExample : convert each of the following decimal numbers into a fraction in lowest term:<\/p>\n

        \n
      1. 0.067 (b) 0.64\n<\/li>\n<\/ol>\n

        Solution
        \n(a) 0.067 = (3 digits after the decimal point i.e divide by 1000)
        \n(b) 0.64 = (as above information) divide through by 4 =
        \nCONVERTING PERCENTAGE TO FRACTIONS
        \n<\/strong>PERCENTAGE IS A SPECIAL TYPE OF FRACTION WITH 100 AS DENOMINATOR. THUS, TO CHANGE A PERCENTAGE TO A FRACTION, DIVIE BY 100.(%)
        \nExample 1: express each of the following as a fraction in its simplest form:<\/p>\n

          \n
        1. 30% (b) 45% (c) 16<\/strong> 1\/2 %\n<\/li>\n<\/ol>\n

          Solution<\/p>\n

            \n
          1. 30% = 30\/100 i.e the zeros cancel each other. the answer is 3\/10\n<\/li>\n
          2. 45% = 45\/100 i.e 5 divide both it gives 9 \/ 20.\n<\/li>\n
          3. 16 \u00bd = 39\/200 i.e you change the mixed number to improper fraction and then multiply it by %.\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
