A)

 \\  \large{ \frac{45}{63} } =  \frac{45 \div 9}{63 \div 9}  =  \large \boxed{  \: \red{ \frac{5}{7} \:  }}

B)

 \\  \large{ \frac{75}{30} } =  \frac{75 \div 15}{30 \div 15}  =  \large \boxed{  \: \red{ \frac{5}{2} \:  }}

C)

 \\  \large{ \frac{42}{105} } =  \frac{42 \div 21}{105\div 21 \:  \: }  =  \large \boxed{  \: \red{ \frac{2}{5} \:  }}

D)

 \\  \large \frac{256}{512}  =   \frac{256 \div 256}{512 \div 256}  =  \large \boxed{ \red{  \: \frac{1}{2}  \: }}

E)

 \\  \large \frac{512}{1024}  =   \frac{512 \div 512}{1024 \div 512 \: }  =  \large \boxed{ \red{  \: \frac{1}{2}  \: }}
