Noralie is making a necklace using a total of 48 beads. All of the beads will be either blue or yellow. She plans to use 1/3 as many yellow beads as blue beads. How many of each color bead will she use

Since there are a total of 48 beads and each bead will either be blue or yellow, in order to find out how many of each colour bead she will use, do the following:

Divide 48 by 3 to get 16 yellow beads.

Now that you know how many yellow beads there are, just subtract that from 48:

48 - 16 = 32

Therefore, she will use 16 yellow beads and 32 blue beads.
