**Multiplicative Inverse of 0.8**

To find the multiplicative inverse of a number, we need to determine a number that, when multiplied by the given number, results in the product being equal to 1. The multiplicative inverse is also known as the reciprocal of a number.

**Step 1: Understanding Multiplicative Inverse**

The multiplicative inverse of a number is a value that, when multiplied by the given number, yields a product of 1. In other words, it is the number that "undoes" the effect of multiplication.

For example, if we multiply a number x by its multiplicative inverse (1/x), the result will always be 1: x * (1/x) = 1.

**Step 2: Calculating the Multiplicative Inverse of 0.8**

To find the multiplicative inverse of 0.8, we need to determine a number that, when multiplied by 0.8, yields a product of 1.

Let's assume the multiplicative inverse of 0.8 is y. Therefore, we have the equation:

0.8 * y = 1

To solve for y, we can rearrange the equation:

y = 1 / 0.8

**Step 3: Simplifying the Expression**

To simplify the expression, we divide 1 by 0.8:

y = 1 ÷ 0.8

Dividing 1 by 0.8 gives us the value of y:

y = 1.25

Therefore, the multiplicative inverse of 0.8 is 1.25.
