Divide Decimal Numbers using the Area Model 5-108

Use the area model to divide by thinking of division as multiplication with an unknown factor or side length. What's 65.6 ÷ 4? 4 x __ = 65.6? Apply the distributive property by breaking the total area into partial areas. Find and add partial side lengths to get the total side length. 65.6 ÷ 4 = (40+24+1.6) ÷ 4 = 10+6+.4 = 16.4.
