Number of boys is 54 and number of girls is 9.
Step-by-step explanation:
Given,
The ratio of boys to girls in a group is 6:1.
And there are 45 more boys than girls.
To find the number of boys and girls.
Let,
Number of boys = 6x
Number of girls = x
According to the problem,
6x = 45+x
or, 6x - x = 45
or, 5x = 45
or, x = [tex]\frac{45}{5}[/tex]
or, x = 9
So,
Number of boys = 6×9 = 54
Number of girls = 9
