Question

Write a word problem that involves combining three equal groups

Answer 1

Combining three equal groups means that we will mainly depend on multiplying the quantity by 3 to get the total

Examples are shown below:
1- Mrs Nadia teaches three classes. Each class has 25 student. How many students does Mrs Nadia teach in total?
In this problem we will be combining three equal groups of students where each group has 25 students, therefore:
Total number of students = 3 * 25 = 75 students

2- John has three bags of candies. Each bag contains 10 pieces of candies. How many candies does John has?
In this problem we will be combining three equal groups of candies where each group has 10 pieces, therefore:
Total number of candies = 3 * 10 = 30 candies

Hope this helps :)

Answer 2

By "three equal groups" I'm going to assume you mean three sets of different things with the same amount in each.

Word problem:

Josh went to the grocery store to buy fruit for smoothies. He bought 6 oranges, 6 apples, and 6 pears. How many fruits did he buy all together? What fraction of all of the fruits are the oranges?
