Number system!!!! xy is a number that is divided by ab where xy 3 years ago

since., $\frac{ xy }{ ab } = 0$ And $xy < ab$ So they answer is very simple $\frac{ xy }{ ab } = 0 => \frac{ xy }{ 1} = 0 \times ab = 0$ so ab can be any no where xy is 0 and 0 divided by any no is either zero or considered infinity Therfore ab can also be taken as 1 @aryandecoolest

any number that divides 0 always yields zero no matter what that number is..

See : $\frac{ xy }{ ab } = 0.xyxyxyxyxyx.......$ where, $xy < ab$ we know that quantity : 0.xyxyxyxyxyxy........ is Irrational Therefore it can also be written as: $\frac{ xy }{ 100 } +\frac{ xy }{ 1000 } + \frac{ xy }{ 10000 } + \frac{ xy }{100000}+...$ Now takin' $\frac{ xy }{ 100 }$ as common Therefore: $\frac{ xy }{ 100 }\left( 1 + \frac{ 1 }{ 10 } + \frac{ 1 }{ 100 } + \frac{ 1 }{ 1000 } + .. \right)$ $=\frac{ xy }{ 100} \times \frac{ 1 }{ (1 - 100)}$ Remember convergence/divergence of power series ! $= \frac{ xy }{ 99 }$ Therefore ,we conclude that: $\frac{ xy }{ ab } = 0.xyxyxyxyxy... = \frac{ xy }{ 99}$ Therefore ab is: $ab = 99$ @aryandecoolest
