Given:
Total students in the fourth grade = 78 students
Number of Girl students = 39
Solution:
We can determine how many number of boys in the fourth grade and the percentage of girls and boys, by dividing their number with the total number.
Number of boys = 78 - 39
Number of boys = 39
Percentage: = 39/79
=0.494
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (49.4)(100)
= 49.4%
The percentage of boys and girls are 49.4% or almost 50%
