Question

In a college, out of $$4320$$ students, $$2300$$ are girls.

Find the ratio of number of boys to the number of girls.

Answer 1

Total number of students$$=4320$$

Number of girls$$=2300$$

Number of boys$$=4320-2300=2020$$

Required ratio$$=\dfrac{2020}{2300}=\dfrac{2\times 2\times 5\times 101}{2\times 2\times 5\times 115}=\dfrac{101}{115}$$.
