Sam has 72 muffins, which he needs to box up, 9 of which are blueberry, into boxes of a dozen. How many boxes does he need.
72 / 12 = ?
To determine the number of boxes Sam needs, you must divide the total number of muffins by the number of muffins per box.
First, find the number of blueberry muffins, which is 9.
Next, subtract the number of blueberry muffins from the total number of muffins to find the remaining muffins: 72 - 9 = 63.
Since each box contains a dozen muffins, and a dozen is equal to 12, divide the remaining muffins by 12: 63 ÷ 12 = 5.25.
Since you cannot have fractional boxes, Sam would need to round up to the nearest whole number. Therefore, Sam needs 6 boxes in total to box up all 72 muffins.
