Evaluate the numerator using the order of operations (BODMAS/PEMDAS).

$$8 \div 2 + 12 \times 9 - 4 \times 6$$

Perform division and multiplication first:

$$4 + 108 - 24$$

Perform addition and subtraction from left to right:

$$112 - 24 = 88$$

$$56 \div 7(2)$$

Perform division first:

$$8(2)$$

Perform multiplication:

$$16$$

$$\frac{88}{16}$$

Simplify the fraction:

$$\frac{88}{16} = \frac{11 \times 8}{2 \times 8} = \frac{11}{2} = 5.5$$

The evaluated expression is 5.5.
