To evaluate the expression (-frac{4}{5} – frac{1}{5} + frac{1}{2} div -frac{1}{4}), we’ll follow the order of operations (PEMDAS/BODMAS).
1. Division first:
[
frac{1}{2} div -frac{1}{4} = frac{1}{2} times -4 = -2
]
2. Now substitute back into the expression:
[
-frac{4}{5} – frac{1}{5} – 2
]
3. Combine the fractions:
[
-frac{4}{5} – frac{1}{5} = -frac{5}{5} = -1
]
4. Combine with the whole number:
[
-1 – 2 = -3
]
So, the evaluated expression is (-3).
