i need the answer the this problem help!?

Question

ok so heres the problem it says segment bc is how much longer then segment ab. so it shows the problem in inches. segment ab is 1 and 1 6th long and bc is at the one and one sitxth line and goes all the way to the four inch line. I cant figure out how much longer bc is then ab! This sounds stupid but i need this answer.

Answer 1

AB is 1 1/6
AC is 4

BC would be the difference between AC and AB:
BC = 4 - 1 1/6 = 2 5/6

But they ask for the difference between BC and AC:
BC - AC
= 2 5/6 - 1 1/6
= 1 4/6
= 1 2/3 inches longer

Answer 2

Then we know that ac=4 in.

bc = ac - ab

so, bc = 4 - 1 and 1/6

so, bc = 2 and 5/6 (or 17/6) inches


So then bc is 10/6 or 1 and 2/3 inches longer than ab

Answer 3

bc is 4inches minus ab 1 1/16 which is 2 15/16 then you subtract 1 1/116 from 2 15/16 which equals 1 14/16 which equals 1 7/8 inches
