4/3+(-8 1/9+8/5•3 1/8):7/8=0,875
Let’s evaluate the expression 4/3 + (-8 1/9 + 8/5 · 3 1/8) : 7/8
Convert mixed numbers: -8 1/9 = -73/9 3 1/8 = 25/8
Compute the product: (8/5) · (25/8) = 200/40 = 5
Sum inside the parentheses: -73/9 + 5 = -73/9 + 45/9 = -28/9
Divide by 7/8: (-28/9) ÷ (7/8) = (-28/9) · (8/7) = -224/63 = -32/9
Add 4/3: 4/3 + (-32/9) = 12/9 - 32/9 = -20/9
Decimal: -20/9 ≈ -2.222...
So the expression equals -20/9 (about -2.222), not 0.875. If you intended a different grouping, let me know and I’ll recalculate.
