Alyson has 46 beads to make bracelets. each bracelets has 5 beads. how many more beads does alyson need so that all the beads she has are used? explain.

First decide the remainder of how many beads she has left over after she makes as many bracelets as she can. 
46/5=9 and 1/5
So the remainder 1/5 means that she has 1 bead left over after making 9 bracelets. 
So to finish all her beads and make her final bracelet, she needs 5-1 or 4 more beads to finish all of her beads. 
Hope this helps.
