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 comparing 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.
