The number of boys in a school is 120. If the
Ratio of boys to girls is 2:3, find the total number of student in the school
Let x be the number of girls in the school.
The total number of students in the school is x + 120.
The ratio of boys to girls is 2:3, or 2/3.
So, (120 / x) = (2 / 3).
Cross-multiplying, we get 2x = 120 * 3,
2x = 360,
x = 360 / 2,
x = 180.
Therefore, the total number of students in the school is 180 + 120 = <<180+120=300>>300. Answer: \boxed{300}.
