Dividing Decimals Concepts

In lesson 10, students learned to divide decimals by decimals. The teacher explained the importance of understanding place values and converting decimals to whole numbers using powers of 10. Two example problems were solved: dividing 8.32 by 3.2 and 115.5 by 77. The process involved converting the divisor to a whole number, performing the division, and verifying the result by multiplying the quotient by the divisor to ensure it matches the original dividend.

What is the first step when dividing decimals by decimals?

• Convert the divisor to a whole number

• Multiply the decimals

• Add zeros to the dividend

• Subtract the decimals

How can you convert a decimal divisor to a whole number?

• By multiplying by a power of 10

• By subtracting decimals

• By dividing by 10

• By adding zeros

What is the result of 8.32 divided by 3.2?

• 1.6

• 3.6

• 4.6

• 2.6

Why is it important to multiply the quotient by the divisor after dividing?

• To simplify the divisor

• To convert the quotient to a whole number

• To find the remainder

• To check if the quotient is correct

In the example of 115.5 divided by 77, what is the quotient?

• 2.5

• 1.5

• 4.5

What is the purpose of 'beaming the decimal up' in division?

• To align the decimal points

• To simplify the divisor

• To find the remainder

• To convert the dividend to a whole number

How many times does 77 fit into 385 in the division example?

What is the power of 10 used to convert 0.77 to a whole number?

• 100

• 10000

• 1000

• 10

What is the final step to ensure the division result is correct?

• Add the divisor to the quotient

• Divide the quotient by the divisor

• Multiply the quotient by the divisor

• Subtract the divisor from the quotient
