Answer (1)

12 zippers ​

Explanation

Understanding the Problem Let's break down how many zippers each person brings to the show. Peter brings 5 zippers, Jenny brings 3 zippers, and Rita brings 5 2 ​ of a set of 10 zippers.

Calculating Rita's Contribution First, we need to calculate how many zippers Rita provides. To do this, we multiply 5 2 ​ by 10: 5 2 ​ × 10 = 5 2 × 10 ​ = 5 20 ​ = 4 So, Rita brings 4 zippers.

Finding the Total Number of Zippers Now, we add the number of zippers each person brings to find the total number of zippers: 5 + 3 + 4 = 12 Therefore, they have a total of 12 zippers for the show.


Examples
Imagine you're organizing a craft fair and need zippers for various projects. Peter provides 5 zippers, Jenny contributes 3, and Rita offers 2/5 of a set of 10 zippers. To determine the total number of zippers available, you calculate Rita's contribution as (2/5) * 10 = 4 zippers. Adding each person's contribution, you find a total of 5 + 3 + 4 = 12 zippers. This calculation ensures you have enough supplies for all the craft projects at the fair.
