Answer 1

ANSWER:

abc-cba=99(a-c)

Step-by-step explanation:

GIVEN:

a>c

TO PROVE:

abc-cba=99(a-c)

PROOF:

abc=100a + 10b + c .............(i) ( By using property 3 )

cba=100c + 10b + c ..............(ii) (By using property 3 )

Subtracting equation (ii) by (i), we get

abc-cba = 100a+c-100c-a

abc-cba = 99a -99c

abc-cba = 99(a-c)
