Decimal Division with Partial Quotients

This video tutorial covers the division of decimals using the partial quotients method. It begins with an introduction to the concept and proceeds with three examples: dividing 16.20 by 4, 119.6 by 23, and 0.648 by 0.9. Each example demonstrates the step-by-step process, including how to handle decimals and align them correctly in the final answer. The tutorial emphasizes the importance of ignoring decimals during calculations and adjusting them at the end to ensure accurate results.

What is the first step when dividing decimals using the partial quotients method?

• Multiply both numbers by 10.

• Subtract the smaller number from the larger number.

• Ignore the decimal point initially.

• Move the decimal point in the divisor.

In the example of 16.20 ÷ 4, what is the first partial quotient used?

• 200

• 100

• 400

• 50

When dividing 16.20 by 4, what is the final answer?

• 4.05

• 4.5

• 0.45

• 40.5

In the example of 119.6 ÷ 23, what is the first partial quotient used?

• 10

• 20

• 30

• 40

What is the final answer for 119.6 ÷ 23?

• 5.2

• 0.52

• 52

• 2.52

When dividing 0.648 by 0.9, what is the first step?

• Move the decimal point in both numbers.

• Subtract the smaller number from the larger number.

• Multiply both numbers by 10.

• Ignore the decimal point.

In the example of 0.648 ÷ 0.9, what is the first partial quotient used?

• 63

• 70

• 630

• 7

What is the final answer for 0.648 ÷ 0.9?

• 0.072

• 72

• 7.2

• 0.72

What should you do with the decimal point in the dividend when the divisor is a whole number?

• Move it to the left.

• Ignore it until the end.

• Remove it completely.

• Move it to the right.

What is the key step to ensure the value of numbers remains unchanged when moving the decimal point?

• Move the decimal point in the divisor only.

• Move the decimal point in the dividend only.

• Move the decimal point in both the divisor and dividend.

• Do not move the decimal point at all.
