(h) \( \frac{8}{-5} \cdot \frac{-1}{-2}+(-2,5)= \)

Calculate or simplify the expression \( \frac{8}{-5} \cdot \frac{-1}{-2}+(-2.5) \). Calculate the value by following steps: - step0: Calculate: \(\frac{8}{-5}\times \frac{-1}{-2}+\left(-2.5\right)\) - step1: Reduce the numbers: \(\frac{4}{5}\times \frac{1}{-1}+\left(-2.5\right)\) - step2: Remove the parentheses: \(\frac{4}{5}\times \frac{1}{-1}-2.5\) - step3: Divide the terms: \(\frac{4}{5}\left(-1\right)-2.5\) - step4: Multiply the numbers: \(-\frac{4}{5}-2.5\) - step5: Convert the expressions: \(-\frac{4}{5}-\frac{5}{2}\) - step6: Reduce fractions to a common denominator: \(-\frac{4\times 2}{5\times 2}-\frac{5\times 5}{2\times 5}\) - step7: Multiply the numbers: \(-\frac{4\times 2}{10}-\frac{5\times 5}{2\times 5}\) - step8: Multiply the numbers: \(-\frac{4\times 2}{10}-\frac{5\times 5}{10}\) - step9: Transform the expression: \(\frac{-4\times 2-5\times 5}{10}\) - step10: Multiply the numbers: \(\frac{-8-5\times 5}{10}\) - step11: Multiply the numbers: \(\frac{-8-25}{10}\) - step12: Subtract the numbers: \(\frac{-33}{10}\) - step13: Rewrite the fraction: \(-\frac{33}{10}\) La valeur de \( \frac{8}{-5} \cdot \frac{-1}{-2}+(-2.5) \) est de -3.3.
