Final answer:
Marco needs to draw 3 boxes to represent the digits of the dividend in the division problem 285 ÷ 5.
Step-by-step explanation:
To solve the division problem 285 ÷ 5, Marco can use equal sharing to divide the number of objects equally. In this case, the objects are the digits of the dividend (285) and the sharing is done by drawing boxes. Marco needs to draw boxes to represent each digit of the dividend, starting from the leftmost digit. Since the dividend has 3 digits (2, 8, 5), Marco needs to draw 3 boxes.
Equal sharing involves dividing a quantity equally among a certain number of groups. In this case, Marco wants to solve the equation
285÷5
285÷5. To determine how many boxes (groups) he needs, he can set up the division like this:
