6/15 . as 2/15 plus 6/15 is 8/15, which is greater than 1/2
5.104+4.103+7.10+1=
9.207+7.10+1=
16.307+1=
17.307
to prove that 6720. Sin 40. Sin 60. 80 equals 3 you'd have to divide 16 by 20 multiply subtract both sides by 3 which is 24x + 6x + 8x + -14 equals 40 40 + 20 equals 16 - -40 equals 80 which equals to 3
