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.
So all you do is put it as a number over 100, and then put that number behind the decimal. (BEWARE! If you have a value over 10 or 1000 or any other number of that sort, then it will work too. Just make sure the number's place corresponds to the value it is "over" ---> .1 is in the 10ths place, so it would be . .245 is in the 1000ths place so it would be )
HOPE THIS WAS HELPFUL! If so, please rate my answer!
8/ (1 1/2) = 36/x....8 muffins to 1 1/2 tsp = 36 ( 3 doz) muffins to x tsp this is a proportion, so we cross multiply (8)(x) = (1 1/2)(36) 8x = 3/2 * 36 8x = 108/2 8x = 54 x = 54/8 x = 6 3/4 <=== 6 3/4 tsps are needed to make 3 doz muffins
