Points A, B, C, and D and lie on a line in alphabetical order. If AB: BD =5:7 and AC: CD = 18:11, determine the ratio AB: BC : CD
There are 29 * 12 = 348 parts to the segment
AB = ( 5/12) *348 = 145/348
BD = (7/12) * 348 = 203 /348
AC = (18/29 ) * 348 = 216/ 348
CD = ( 11/ 29 ) * 348 = 132/348
A B C D
145 71 132
AB : BC : CD = 145 : 71 : 132
