12/75. First,You Divide The Numerator By The Denominator.Since 75 Can't Go Into 12 Evenly,You Have To Make 12 Into 12.0.Then,You Say"75 Can Go Into 12.0 1 Time" Which'll Be 45 Left Over.Then,You Add Another 0 Behind 45,Which'll Be 450.Then You See How Many Times 75 Can Go Into 450,Which Is 6 Times Evenly.The Answer Is 0.16.To Check Your Work,You'd Multiply 75 by 0.16,Which Gets You Back to 12.
