the best way is to compare the fraction part of mixed fraction in given option
Lets first compare A and B
fraction part of option A =9/11 and that of B = 4/5
find the equivalent option of these two fraction
For A (9/11) ×(5/5) = 45/55 and for B (4/5) ×(11/11) = 44/55
so fraction part of option A that is 45/55 is greater than option B that is 44/55
hence option A is greater than option B
Now compare fraction of option A with Option C ,
equivalent fraction of A = (9/11)×(3/3) = 27/33 and equivalent fraction of C = (2/3)*(11/11)
= 22/33 , hence option A (27/33) is also greater than option C ( 22/33 )
Finally lets compare Fraction part of A and D .
Equivalent fraction of A = (9/11) ×(8/8) = 72/88 and for D = (7/8) × (11/11) = 77/88
fraction of D is greater that fraction of A .
Hence D that is 2 7/8 is greatest and is the best deal.
in above solution we have make the denominators same to compare two fraction value.
