Answer:
Since,
[tex]\frac{45}{45}=1[/tex]
Thus, the sign in option 'a' would be '='.
[tex]\frac{6}{3}=2[/tex]
[tex]\implies 1<\frac{6}{3}[/tex]
Thus, the sign in option 'b' would be '<',
[tex]\frac{2}{7}\approx 0.2857[/tex]
[tex]\implies \frac{2}{7}<1[/tex]
Thus, the sign in option 'c' would be '<',
[tex]\frac{64}{23}\approx 0.2857[/tex]
[tex]\implies \frac{64}{23}<1[/tex]
Thus, the sign in option 'd' would be '<'
