Fraction $=$ Value $/$ TotalFraction of boys $=$ No. of boys in the class $/$ Total No. of studentsTotal No. of students $=$ No. of boys + No. of girls $=12+18=30$No. of boys $=12$$\Rightarrow$ fraction of boys $=\frac{12}{30}=\frac{2}{5}$ (Thus 6 goes into 12, 2 times and 30, 5 times)NOTE: Fraction of girls $=\frac{18}{30}=\frac{3}{5}$ (Thus 6 goes into 18,3 times and 30,5 times)The sum of all fractions should be 1Verify: Fraction of boys + Fraction of girls $=\frac{2}{5}+\frac{3}{5}=\frac{2+3}{5}=\frac{5}{5}=1$
