-5,6 : (-8)

To simplify the expression \(-5.6 : (-8)\), we can interpret the colon (:) as division. Thus, the expression can be rewritten as:

\[ -5.6 \div (-8) \]

When dividing two negative numbers, the result is positive. So we calculate:

\[ -5.6 \div (-8) = \frac{-5.6}{-8} = \frac{5.6}{8} \]

Now, let's compute \( \frac{5.6}{8} \):

Divide \(5.6\) by \(8\):

\[ 5.6 \div 8 = 0.7 \]

Therefore,

\[ -5.6 : (-8) = 0.7 \]
