In a beaded necklace 3/12 of the beads are blue and 1/3 are green. what fraction are blue n green.

7/12

Step-by-step explanation:

3/12 blue

1/3 = 4/12 green

blue + green

3/12 + 4/12 = 7/12

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
