Answer 1

abc= 1

1/(1+ b+ c^-1) = c/( c+ bc + 1)

bc = 1/a

c/( c + 1/a +1)

ca/( ca + a + 1)

1/( 1+ a+ b^-1) = b/( b + ab +1)

ab = 1/c

= b/( 1/ca. + 1/c + 1)

= bca /( 1+ a + ca)

= 1/( 1+ a+ ca)

1/( 1+ c+ a^-1) = a/( a+ ca +1)

So

ca/( ca+ a+ 1) + 1/( 1+ a+ ca) + a/(a+ ca+ 1)

ca+ 1+ a)/( ca+ a+ 1)

(2) 1 is correct✌✌✌
