• Multiply the decimals directly

When multiplying decimals, what should you do with the decimal points initially?

• Subtract them

• Ignore them

• Multiply them

• Add them together

How do you determine where to place the decimal point in the final answer?

• Always place it at the end

• Use the same number of decimal places as the first factor

• Count the total decimal places in the factors

• Place it randomly

Why does the standard algorithm for multiplying decimals work?

• It only works for whole numbers

• It ignores the decimal points completely

• It is based on the concept of fraction multiplication

• It uses addition instead of multiplication

What should you do after estimating and multiplying the decimals?

• Ignore the estimate

• Subtract the estimate from the answer

• Add more decimal places
