Mr rawlings has 60 cookies he wants to give each of his grandchildren the same number of cookies what is the number of whole cookies he can give to each child after he gives them the cookies how many will he have left.

Basically, you keep going after you hit the decimal point. 

You have 60 cookies to divide among 16 grandchildren. 

60 ÷ 16 = 3 with a remainder of 12 

To continue past the decimal point, multiply the remainder by 10 and divide it by your divisor. 

12 ÷ 16 becomes 120 ÷ 16, and divided by 10 to put it in the first column past the decimal point. 
120 ÷ 16 = 7, with a remainder of 8. 
The first digit after the decimal point is 7. 

Add another zero to the 8 to get 80 
80 ÷ 16 = 5, with no remainder. 
The second digit after the decimal point is 7. 

So the answer is 3.75 cookies per grandchild.

Iam thinking the answer is a.) knew
