To express the fraction \(-\frac{40}{56}\) as a rational number with a numerator of \(-5\), follow these steps:
Start with the given fraction:
\(-\frac{40}{56}\)
Simplify the fraction by finding the greatest common divisor (GCD) of 40 and 56. The GCD of 40 and 56 is 8.
Divide both the numerator and the denominator by their GCD:
\(\frac{-40 \div 8}{56 \div 8} = \frac{-5}{7}\)
The simplified form of the fraction is \(-\frac{5}{7}\), which matches the requirement of having the numerator as \(-5\).
Thus, the answer is \(-\frac{5}{7}\), confirming that \(-\frac{5}{7}\) is equivalent to the given fraction \(-\frac{40}{56}\) when simplified.
By analyzing all the options, we can conclude that the correct option is \(-\frac{5}{7}\).
