Answer 2

Let's calculate the products for each of the given expressions:

1. -9.88 * 10 = -98.8

2. -90.71 * 1.5 = -136.065

3. 101.03 * (-0.01) = -1.0103

4. 3.22 * (-0.4) = -1.288

5. To multiply mixed numbers, first convert them to improper fractions:

1 целая 3/8 = 8/8 + 3/8 = 11/8 -1 целая 15/33 = -33/33 - 15/33 = -48/33

Now, multiply the improper fractions:

(11/8) * (-48/33) = -528/264 = -2

So, 1 целая 3/8 * (-1 целая 15/33) = -2

6. To multiply fractions, simply multiply the numerators and denominators:

(-11/13) * (-52/55) = (11 * 52) / (13 * 55) = 572/715

So, -11/13 * -52/55 = 572/715

Note: In some of these calculations, I rounded the results to a reasonable number of decimal places. If you need more decimal places, you can use a calculator for greater precision.
