Answer 1

Hello friend
------------------

=) In example

=) a/b = 7/3

=) a/7 = b/3 = k.......( Using alternando)

=) a = 7k, b= 3k

Now put the values of a and b.

=) 5a + 3b/5a - 3b

=) 5*7k + 3*3k/ 5*7k - 3*3k

=) 35k + 9k/35k -9k

=) 44k/26k

=) 44/26

=) 22/13


: 5a+3b/5a-3b = 22/13

Hope this will helps you.

Thanks.
