A baker will put 84 carrot muffins in boxes that hold 6 muffins each. How many boxes will the baker fill?

To solve, divide 84 muffins into 6 groups.

Find 84 ÷ 6.

Estimate 84 ÷ 6 80 ÷ 5 = 16

Step 1Divide the tens. Can 8 tens be divided among 6? Yes.

6 841

– 62

Step 2Bring down the ones. Divide the ones. Can 24 ones be divided among 6? Yes.

6 841

– 6224–0

Divide: 8 ÷ 6Multiply: 1 × 6Subtract: 8 – 6Compare: 2 < 6

Divide: 24 ÷ 6Multiply: 4 × 6Subtract: 24 – 24Compare: 0 < 6

Answer: So, 84 carrot muffins will fit in 14 boxes. This is close to the estimate, 16. So, the answer is reasonable.
