Question

Roxanne has 1/2 as many beads as Sherrie. The number of beads Sherrie has is 4/5 that of Ting Ting's. Ting Ting has 165 beads. How many more beds does Ting Ting have than Roxanne?

Answer 1

Ting Ting has 99 beads more than Roxanne.

Ting Ting's = 165 beads

Sherrie : has 4/5 beads that of Ting Ting's
165 * 4/5 = 660 / 5 = 132 beads

Roxanne : has 1/2 as many beads as Sherrie
132 * 1/2 = 132 / 2 = 66 beads

Ting Ting's beads - Roxanne's beads  = difference
165 - 66 = 99 beads.

Ting Ting has 99 beads more than Roxanne.

Answer 2

Roxanne has 66 beads
Sherri has 132 beads
ting ting has 165 beads
