notes

Percentage:

  • Per cent is derived from the Latin word ‘per centum’ meaning ‘per hundred’.

  • Percentages are numerators of fractions with denominator 100.

  • The percent is represented by the symbol % and means hundredths too. That is 1% means 1 out of hundred or one-hundredths.

  • It can be written as: 1% = `1/100` = 0.01.

  • For example, `40/100 = 40 % and 90/100 = 90%`

Percentages when the total is not hundred:

  • When a ratio is not expressed in fraction of 100, we need to convert the fraction to an equivalent fraction with denominator 100.

  • Example:
    Consider a fraction `12/20`.

    Multiply the numerator and denominator by 5.

    = `12/20 = (12 xx 5)/(20 xx 5) = 60/100 = 60%`.

    or
    Multiply by 100.

    = `12/20 xx 100 = 12 xx 5 = 60%`
    or
    Multiply the numerator and denominator by 100.

    = `12/20 xx 100/100 = 60%`.
