Answer :
Hello
To slolve this question, we have to find the numbers that share the ratio 5 / 7
Or alternatively, if we divide the numbers equally with a single number, we would get 5/7
Let's try out 57 / 75
the only number that seems to go in this would be 3
[tex]\frac{57}{75}=\frac{19}{25}[/tex]This is wrong
Let's try out option B
But from mere looking at option B, it is out of the question because eventually, the numerator would be larger than the denominator and that makes it out of options
With option C
Let's divide both numbers by 9
[tex]\frac{45}{63}=\frac{5}{7}[/tex]This is correct and is the right option for this question.
From the calculations above, it is evident that the answer to this question is option C
