Ilya split up the area of a rectangle to help him solve the division equation 4{,}348 \div 6=?4,348÷6=?4, comma, 348, divided by, 6, equals, question mark. He splits the rectangle into parts that are easy to divide by 666 and a remainder: Area model split into 4 parts, each with a width of 6 units. From top to bottom the parts have a height of A units and an area of 4,200 square units; a height of B units and an area of 120 square units; a height of C units and an area of 24 square units; an unlabeled height and an area of 4 square units. A brace labeled H spans the top 3 parts. Complete the equations. a=a=a, equals units b=b=b, equals units c=c=c, equals units h =h=h, equals units 4{,}348 \div 6 =4,348÷6=4, comma, 348, divided by, 6, equals remainder
