Question

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

Answer 1

9 beads are purple

Explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

so

`18((3)/(6))=9\ beads`

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

`(3)/(6)=(1)/(2)=0.50*100=50\%`

so

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
