Answer 1

To multiply −25 by 310, we simply multiply the absolute values of the numbers and determine the sign of the product.

|-25| x |310| = 25 x 310 = 7750

Since one of the factors is negative, the product is negative.

Therefore, the answer is -7750.

Answer 3

To multiply -25 by 310, you multiply the absolute values of the numbers and determine the sign of the product.

|-25| x |310| = 25 x 310 = 7750

Since one of the factors is negative, the product is negative.

Therefore, the answer is -7750.

Answer 5

To multiply -2/5 by 3/10, you simply multiply the numerators and denominators separately:

(-2/5) x (3/10) = (-2 x 3) / (5 x 10) = -6/50

The answer, -6/50, can be simplified by dividing the numerator and denominator by their greatest common divisor, which is 2:

-6 divided by 2 = -3
50 divided by 2 = 25

Therefore, the answer, in simplest form, is -3/25.

−2 1/2

Answer 7

To multiply 4 by -5/8, you multiply the whole number by the numerator:

4 x (-5) = -20

Then, you keep the same denominator:

-20/8

This can be simplified by dividing the numerator and denominator by their greatest common divisor, which is 4:

-20 divided by 4 = -5
8 divided by 4 = 2

Therefore, the answer, in simplest form, is -5/2. However, since -5/2 is an improper fraction, it can be written as a mixed number by dividing the numerator by the denominator:

-5 divided by 2 = -2, with a remainder of 1.

Therefore, the mixed number in simplest form is -2 1/2.

Answer 13

To multiply -2 1/2 by -1 3/5, you need to convert the mixed numbers to improper fractions first.

-2 1/2 = -5/2
-1 3/5 = -8/5

Then, you multiply the two fractions:

(-5/2) x (-8/5) = 40/10 = 4

Therefore, the answer as a decimal is 4.
