a) Find the product.
(−1.15) ⋅ 3.2
b) Explain in words how you determined the sign of your answer.
I don't know what to do for A, but this is my answer for B:
Since both factors are different signs, I know the product is going to be negative.
Multiply the same way you'd multiply if there were no decimal points. I assume you could multiply it if it looked like this.
115
x 32
______
After you get the answer put the correct sign and decimal point in place.
(−1.15) * 3.2 =

I appreciate that Ms.Sue, but I need to actually put the steps, not just say "the answer is -3.68" If it did I would have done that already.
And I don't know where to start with said steps.
But thank you anyway.
To find the product of (-1.15) ⋅ 3.2, you need to multiply these two numbers together.
Step 1: Multiply the absolute values of the numbers: 1.15 ⋅ 3.2 = 3.68.
Step 2: Determine the sign of the result:
- If both factors have the same sign (either both positive or both negative), then the product will be positive.
- If the factors have different signs (one positive and one negative), then the product will be negative.
In this case, (-1.15) is negative and 3.2 is positive, so the product is negative.
Therefore, (-1.15) ⋅ 3.2 = -3.68.
So, the product is -3.68.
For part b) of the question, you correctly determined the sign of the answer by observing that the two factors have different signs, which means the product will be negative.
