She will need 24 orange beads. Add 3+2, 5. Divide 60 by 5, 12. So each one of the original five corresponds to twelve beads, and since two of the five were orange, that means she needs 24 orange beads.
Easy. [tex]Add: 3+2=5
Keep adding until you get to 60.
6+4=10, 9+6=15...... 36+24=60
36(blue)+24(orange)=60
Therefore: there are 24 orange beads needed[/tex]
