Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

( x + y )   /  ( x - y )

Step-by-step explanation:

x square - y square / 100

=( x / 10 ) ^2 - ( y / 10 )^2

={( x / 10 )  + ( y / 10 )} . {( x / 10 )  - ( y / 10 )}   { ∵ x^2 - y^2= ( a + b ).( a - b ) }

={ ( x + y ) / 10 } / { ( x - y ) / 10 }

= ( x + y )   /  ( x - y )
