To evaluate ((8 + 22) \div (10 \times 4)), follow the order of operations, also known as PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

[ (8 + 22) \div (10 \times 4) = (30) \div (10 \times 4) ]

[ = 30 \div 40 ]

[ = \frac{30}{40} ]

[ = \frac{3}{4} ]
