Heya !!!!
Let the number of boys be X.
Number of girls = 1/7 of boys = 1/7 X = X/7
Total number of students = 48
Therefore,
Number of boys + Number of girls = Total Number of students
X + X/7 = 48
7X + X/7 = 48
7X + X = 48 × 7
8X = 336
X = 336/8
X = 42
Total Number of boys = X = 42
And,
Number of girls = X/7 = 42/7 = 6
Hope it helpful
