Alternative Division Method Concepts

The video introduces an alternative method for division, which involves multiplying by round numbers and adding them to simplify the process. The method is demonstrated through three examples: dividing 2620 by 20, 2160 by 12, and 2523 by 15. The technique is shown to be easier than traditional division in some cases, though it can become complex with certain numbers. The video concludes with a method to handle remainders by converting them into decimals.

What is the first step in the alternative division method?

• Subtract the divisor

• Divide the numbers directly

• Multiply by round numbers

• Add the numbers

In the example of dividing 2620 by 20, what is the first round number used?

• 50

• 200

• 100

• 10

What is the result of multiplying 20 by 10 in the example of 2620 divided by 20?

• 200

• 400

• 600

• 800

How do you handle the remainder in the alternative division method?

• Subtract it from the dividend

• Add it to the quotient

• Ignore it

• Multiply it by the divisor

In the example of dividing 2160 by 12, what is the first multiplication performed?

• 12 x 20

• 12 x 50

• 12 x 100

• 12 x 10

What is the next step after subtracting 1200 from 2160 in the division by 12 example?

• Multiply by 40

• Multiply by 30

• Multiply by 50

• Multiply by 20

In the challenging example, what is the first round number used for 2523 divided by 15?

• 300

• 200

• 400

• 100

How is the remainder handled in the challenging example of 2523 divided by 15?

• It is multiplied by the divisor

• It is added to the quotient

• It is converted to a decimal

• It is ignored

What is the final quotient in the example of 2523 divided by 15?

• 167.5

• 168.2

• 170.1

• 169.3

What is a potential drawback of the alternative division method?

• It is more complex

• It requires more steps

• It can be difficult to find suitable round numbers

• It always results in a remainder
