To find the number of apples in each box, Jack can set up a division equation. Since he has 4 apples and 4 boxes, he can divide the total number of apples by the number of boxes:
Division Equation: \[ 4 \div 4 = 1 \]
This means each box will contain 1 apple.
To relate this to a multiplication equation, he can also express that the number of boxes multiplied by the number of apples in each box gives the total number of apples:
Multiplication Equation: \[ 4 \times 1 = 4 \]
So, Jack can use the equations \( 4 \div 4 = 1 \) and \( 4 \times 1 = 4 \) to relate the division and multiplication in this scenario. Each box contains 1 apple.
