Answer: 12 girls and 34 boys
Step-by-step explanation:
There are 46 students in total with boys being 3 times the number of girls.
To solve this, assume the total number of girls is x.
In that case the total number of boys will be 3 times that number which is 3x.
Equate this to 46:
x + 3x = 46
4x = 46
x = 46 / 4
x = 11.5
= 12 girls
The number of boys is 3 times that of girls:
= 11.5 * 3
= 34 boys
