Answer 4

To multiply −2/5 by 3 1/0, we first need to convert the mixed number 3 1/0 to an improper fraction.

To do this, we multiply the whole number (3) by the denominator of the fraction (0), and then add the numerator (1):

3 × 0 + 1 = 1

So 3 1/0 is equal to 1/0.

Next, we can multiply the fractions:

−2/5 × 1/0 = (−2 × 1) / (5 × 0) = −2/0

The result is −2/0. However, we cannot leave the answer in this form because division by zero is undefined in mathematics.

Answer 5

Apologies for the error in the previous response. The correct way to multiply −2/5 by 3 1/0 is as follows:

First, we convert the mixed number 3 1/0 to an improper fraction. Since the denominator is 0, this is not possible.

Therefore, we cannot proceed with the multiplication as dividing by zero is undefined.

Answer 6

To multiply 4 by −5/8, we multiply the whole number (4) by the numerator (-5) and divide the product by the denominator (8):

4 * (-5) = -20
-20 / 8 = -2 remainder 4

So, the answer is −2 4/8. However, we can simplify this mixed number:

The fraction 4/8 can be reduced by dividing both the numerator and denominator by their greatest common factor, which is 4:

4 ÷ 4 = 1
8 ÷ 4 = 2

Thus, the simplified form of 4/8 is 1/2.

Therefore, the final answer as a mixed number in simplest form is −2 1/2.

Answer 7

To multiply 6.5 by 0.3, we simply multiply the two decimals together:

6.5 * 0.3 = 1.95

Therefore, the answer is 1.95.
