Question

Kerri said that the product of 3.93 and 0.07 would be about 4 and would have two decimal places. Is she correct? Explain why or why not. Then find the exact product.

Answer 1

Answer: She is not correct.

Step-by-step explanation: The product of two or more numbers means the answer you get when you multiply all values.

So the product of 3.93 and 0.07 means 3.93 x 0.07 and that gives us exactly 0.2751, that is;

3.93 x 0.07 = 0.2751

The answer would have four decimal places and this is because when multiplying figures with decimals, the final result (the product) usually has the combination of decimal places of all values multiplied. Since 3.93 has TWO decimal places and 0.07 has TWO decimal places as well, the product of both numbers would have a combined total of FOUR decimal places.

So the correct answer is not 4, but rather the answer is 0.2751 (with FOUR decimal places)

Answer 2

Answer: She is Wrong

Explanation:

Hi, to answer this question we have to multiply (product means the result of a multiplication) both numbers and see if it is true:

3.93 x 0.07 =0.2751

She is wrong, the number has 4 decimal places and it's not about 4.

It is about 4 if we add both numbers.

3.93+0.07 = 4
