How to Divide a Decimal by a Decimal

In this video, Miss C explains how to divide decimal numbers using long division. The tutorial covers two problems: 7.64 divided by 0.4 and 32.8 divided by 0.16. For each problem, the video demonstrates how to convert the divisor into a whole number by moving the decimal point, ensuring the dividend is adjusted similarly. The video then guides viewers through the division process, emphasizing the steps of dividing, multiplying, subtracting, and bringing down digits. The final answers are 19.1 and 205, respectively.

What is the first step in setting up a division problem with decimals?

• Convert the dividend to a whole number.

• Place the dividend inside the long division box.

• Multiply the divisor by 100.

• Subtract the divisor from the dividend.

Why do we need to convert the divisor into a whole number?

• To balance the equation.

• To ensure the dividend is larger.

• To make the division process easier.

• To avoid decimal points in the quotient.

What must you do to the dividend if you multiply the divisor by 10?

• Subtract 10 from the dividend.

• Multiply the dividend by 10.

• Add a zero to the dividend.

• Divide the dividend by 10.

In the division process, what should you do after subtracting?

• Multiply the result by the divisor.

• Add the divisor to the result.

• Bring down the next digit.

• Move the decimal point.

What is the quotient of the first division problem?

• 19.10

• 18.1

• 19.1

• 19.01

How many places do you move the decimal point for the second problem's divisor?

• Two places to the right.

• Two places to the left.

• One place to the left.

• One place to the right.

What is the final quotient for the second division problem?

• 25.0

• 20.5

• 200.5

• 205
