All three strategies work. Drawing 24 cookies and putting them into 7 equal groups gives 3 cookies to each group, with 3 left over. Dividing 24 by 7 confirms this: 24 ÷ 7 = 3 remainder 3. The equation 7x + 3 = 24 represents 7 friends getting x cookies each, with 3 cookies left over; solving gives x = 3.
