Answer 2

add all bead colors up

42+28+12+18=100

add up yellow and green

42+28=70

now find out how many beads are not yellow or green by subtracting that from 100

100-70=30

so the first answer is 30/100 -> 3/10 -> 30%

now add up red and green beads

28+18=46

so your next answer is

46/100 -> 23/50 -> 46%
