Question

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

Answer 1

Step-by-step explanation:

T = beads of Ting Ting = 165

S = beads of Sherie.

R = beads of Roxanne.

S = 4/5 × T = 4/5 × 165 = 4 × 33 = 132 beads

R = 1/2 × S = 1/2 × 132 = 66 beads

Ting Ting has therefore 165 - 66 = 99 more beads than Roxanne.
