Step-by-step explanation:

Let's round the numbers and find their products:

1. 0.65 rounded to the nearest whole number is 1.

2. 1.39 rounded to the nearest whole number is 1.

3. 0.33 rounded to the nearest whole number is 0.

4. 8.82 rounded to the nearest whole number is 9.

5. 7.8 rounded to the nearest whole number is 8.

Now, let's calculate the products of all pairs:

1. 1 * 1 = 1

2. 1 * 0 = 0

3. 1 * 9 = 9

4. 1 * 8 = 8

5. 0 * 9 = 0

6. 0 * 8 = 0

The two numbers that, when rounded, give a product closest to 5 are 1 and 1 because 1 * 1 equals 1, which is the closest product to 5.
