Mastering Decimal Operations: Addition, Subtraction, Multiplication, and Division

What is the first step when adding decimals?

• Ignore the decimal points

• Start adding from the left

• Line up the decimal points

• Convert to fractions

Why do we use placeholder zeros when adding decimals?

• To make the problem more complex

• To change the value of the decimal

• To make the numbers look bigger

• To line up the decimal places correctly

What should you do if you encounter a zero when subtracting decimals?

• Borrow from the next place value

• Drop the zero

• Add a placeholder zero

• Ignore it

What is a common mistake to avoid when subtracting decimals?

• Ignoring the decimal points

• Adding instead of subtracting

• Multiplying the numbers

• Dropping a number without borrowing

What is the first step when multiplying decimals?

• Divide the numbers

• Line up the decimal points

• Add the numbers

• Remove the decimal points

How do you determine where to place the decimal in the final answer when multiplying decimals?

• Place it at the beginning of the number

• Ignore the decimal

• Count the total digits to the right of the decimal in the original numbers

• Place it at the end of the number

What should you do if the divisor is not a whole number when dividing decimals?

• Ignore the decimal

• Make the divisor a whole number by moving the decimal

• Add zeros to the divisor

• Subtract the decimal

What is the process to follow when dividing decimals?

• Divide, multiply, subtract, bring down, repeat

• Subtract, divide, multiply, bring down, repeat

• Multiply, add, subtract, repeat

• Add, subtract, multiply, divide

What can you add to the end of a decimal to continue the division process without changing its value?

• A decimal point

• A zero

• A two

• A one

What is the final step in the division process to ensure the problem is complete?

• Get a clean cut zero at the end

• Subtract the result

• Multiply the result

• Add more numbers
