There are 31 beads on Avery's necklace. 27 of the beads are pink and the rest are purple. What is the ratio of the number of purple beads to the number of pink beads?

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

the answer for this question is a= 13,622.84

step-by-step explanation:

the answer is 18/9

step-by-step explanation:

-18/-9 = 2

18/9 = 2

same answer.

hope it !
