To find the percentage of girls in the class, we need to know the number of girls in the class.
Given that the total number of pupils in the class is 32 and the number of boys is 12, we can subtract the number of boys from the total number of pupils to find the number of girls.
Number of girls = Total number of pupils - Number of boys
Number of girls = 32 - 12
Number of girls = 20
Now, to find the percentage of girls in the class, we can use the following formula:
Percentage = (Number of girls / Total number of pupils) × 100
Plugging in the values, we get:
Percentage = (20 / 32) × 100
Percentage = 0.625 × 100
Percentage = 62.5%
Therefore, 62.5% of the class are girls.
