A =$\frac{198:2\times 4444\times 2\times 132:25}{33\times 8888:5\times 66:125\times 5}$  

$A=\frac{198\times \frac{1}{2}\times 4444\times 2\times 132\times \frac{1}{25}}{33\times 8888\times \frac{1}{5}\times 66\times \frac{1}{125}\times 5}$

$A=\frac{(66\times 3)\times 4444\times (33\times 4)\times \frac{1}{25}}{33\times (4444\times 2)\times 66\times \frac{1}{125}}$

$A=\frac{3\times 2\times \frac{1}{25}}{\frac{1}{125}}=6\times \frac{1}{25}\times 125=6\times 5=30$
