a) 45/63

b) 75/30

c) 42/105

d) 256/512

e) 512/1024​

Answer 1

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)

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