Respuesta :
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%
42+28+12+18=100
