To find the additive inverse of a number, you need to change the sign of the number. For example, the additive inverse of 5 is -5 and vice versa.

For -8, the additive inverse is 8.

To find the multiplicative inverse of a number, you need to find the reciprocal of the number. The reciprocal of a number is obtained by taking 1 divided by the number. For example, the multiplicative inverse of 3 is 1/3 and vice versa.

For -8, the multiplicative inverse is -1/8.

For 1.5, the additive inverse is -1.5 because changing the sign gives the opposite value.

The multiplicative inverse of 1.5 is 2/3. To find this, you can use the formula:

Multiplicative Inverse = 1 / Number

In this case, the multiplicative inverse is 1 / 1.5 = 2/3.
