Answer 1

hope it help u........

Answer 2

Answer:

$\boxed{5}$

Step-by-step explanation:

Given:

x : y = 3 : 2

$\bf{By\: componendo\: and\: dividendo:}$

if a : b then ( a + b ) : (a - b)

So:

x : y = 3 : 2

==> ( x + y) / (x - y) = (3 + 2 )/( 3 -2)

==> ( x + y ) / ( x - y ) = 5 / 1

==> 5

$\bf{Another\: method}$

x : y = 3 : 2

Let x be 3 k

y is 2 k

So:

(x + y) / (x - y)

==> ( 3 k + 2 k ) / ( 3 k - 2 k )

==> 5 k / k

==> 5

Hope it helps you :-)
