Sophie uses 18 beads to make a necklace.Three sixths of the beads are purple.How many beads are purple

3/6 of the beads are purple

3/6 simplified = 1/2

1/2 of 18, or 18/2 = 9

9 beads are purple

hope this helps

Answer 2

You can solve this using a few different concepts. The easy way that may not always work is to notice that 3/6 is equal to 1/2. Next you can quickly determine what 1/2 of 18 is.

The other method is the harder but always successful Brute force way.
Since there are 18 beads total, and you know 3/6 of them are purple, you need to set up your equation as follows:
$\frac{18}{1} \times \frac{3}{6} = \frac{54}{6} =?$
