Question

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

Answer 1

Answer:

9 beads are purple

Step-by-step 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

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

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

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

so

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
