Dividing Decimals by Whole Numbers Using Visual Models (Example)

The video tutorial explains how to divide 1.64 by 4 using 10x10 arrays. It starts by representing 1.64 with two arrays, shading one whole and 64 hundredths. The process involves dividing these into four equal groups using additional arrays. Columns are distributed evenly among the arrays, and remaining squares are shared to complete the division. The result is that each array represents 0.41, demonstrating that 1.64 divided by 4 equals 0.41.

What is the initial composition of 1.64 in terms of wholes and hundredths?

• 1 whole and 64 hundredths

• 2 wholes and 64 hundredths

• 1 whole and 46 hundredths

• 64 wholes and 1 hundredth

How many arrays are used to divide 1.64 into four equal groups?

• 2 arrays

• 4 arrays

• 6 arrays

• 8 arrays

What is the total number of columns shared among the four arrays?

• 12 columns

• 14 columns

• 16 columns

• 18 columns

After dividing the columns, how many squares remain to be shared?

• 5 squares

• 4 squares

• 3 squares

• 2 squares

What is the final result of dividing 1.64 by 4?

• 0.41

• 0.14

• 0.46

• 0.64
