    ‘Comparing Quantities’, we will look at examples to understand percentages.

    Percentage – Example

    Q. Emma scored 18 out of 25 and Frieda scored 35 out of 50 in their respective exams. Who performed better?

    Solution:

    Method 1: Make the denominators common by taking LCM and compare the numerators.

    Since 50 is a multiple of 25, 50 becomes the LCM of the two numbers.

    Emma

    Frieda

    18 × 2 36

    =

    25 × 2 50

    35

    50

    So comparing the numerators, 36 > 35. Thus, Emma performed better than Frieda.

    Method 2: By percentage.

    Percent means out of 100.

    In Emma’s case to get a 100 in the denominator, multiply the denominator and the numerator by 4.

    Emma

    18 × 4 72

    = = 72%

    25 × 4 100
