Let's solve the equation step by step.

First, we can convert \(0.8\) to a fraction to make it easier to work with.

\[ 0.8 = \frac{8}{10} = \frac{4}{5} \]

Next, we can convert \(0.32\) to a fraction as well:

\[ 0.32 = \frac{32}{100} = \frac{8}{25} \]

Now we can rewrite the original equation, substituting the fractions:

\[ \left(-\frac{12}{25}\right) + \frac{4}{5} = \frac{8}{25} \]

To combine \(-\frac{12}{25}\) and \(\frac{4}{5}\), we need a common denominator. The least common multiple of 25 and 5 is 25:

\[ \frac{4}{5} = \frac{4 \cdot 5}{5 \cdot 5} = \frac{20}{25} \]

Now we rewrite the equation:

\[ -\frac{12}{25} + \frac{20}{25} = \frac{8}{25} \]

Now we can combine the fractions on the left side:

\[ \frac{-12 + 20}{25} = \frac{8}{25} \]

Simplifying the left side gives:

\[ \frac{8}{25} = \frac{8}{25} \]

Thus, the equation is true.

Therefore, the original statement \((-12/25) + 0.8 = 0.32\) is indeed correct.
