$11.16 and $8.96
11.16 = 11 + 16/100
= (11x100)/100 + 16/100
= (1100 + 16)/100
= 1116/100
8.96 = 8 + 96/100
= (8x100)/100 + 96/100
= (800 + 96)/100
= 896/100
So this ratio as a fraction is:
(1116/100) / (896/100)
Which is the same as:
(1116/100) x (100/896) = 1116/896
And this simplified is:
279/224
