What is 0.6 times 0.3?

What is 0.6 times 0.3?

• A. 0.12
• B. 0.06
• C. 0.30
• D. 0.18

Answer: (D)

Multiplying decimals uses the same idea as multiplying integers, then you place the decimal point according to how many digits come after the decimal in the factors. In 0.6 there is one digit after the decimal, and in 0.3 there is one digit after the decimal, so the product should have two digits after the decimal. Multiply 6 by 3 to get 18, then place the decimal two places from the right to get 0.18. You can also see it with fractions: 0.6 is 6/10 and 0.3 is 3/10, so the product is (6×3)/(10×10) = 18/100 = 0.18. So the result is 0.18.
