Dividing Decimals by Whole Numbers Using Visual Models

This video tutorial teaches how to divide a decimal by a whole number using a 10 by 10 array. It begins by explaining the representation of decimals in the array and sets up a division problem of 84/100 divided by 3. The tutorial demonstrates how to distribute columns and handle leftover squares to achieve an even division. The result is verified by checking the total in the arrays, confirming the division is correct. The lesson concludes with a recap of the method used.

What does each square in a 10 by 10 array represent?

• 1/100 of the array

• 1/10 of the array

• 1/2 of the array

• 1/1000 of the array

How many columns are initially shaded to represent 84/100 in the array?

• 10 columns

• 8 columns

• 12 columns

• 4 columns

What is the total number of squares left after distributing the columns among the groups?

• 30 squares

• 24 squares

• 20 squares

• 10 squares

How many squares does each group receive when distributing the leftover squares?

• 7 squares

• 6 squares

• 8 squares

• 9 squares

What is the final result of dividing 84/100 by 3?

• 24/100

• 28/100

• 30/100

• 32/100
