Problem Statement

The problem states that Ira is 21 times younger than her 84-year-old grandmother. We need to determine Ira's age and how many times younger Ira's mother is compared to her grandmother, given that her mother is 42 years old.

Solution

Let's solve the problem step by step:

1. We know that Ira is 21 times younger than her grandmother. To find Ira's age, we need to divide her grandmother's age by 21. - Ira's age = Grandmother's age / 21

2. We also need to find out how many times younger Ira's mother is compared to her grandmother. To do this, we need to calculate the age difference between Ira's mother and grandmother and then divide it by the grandmother's age. - Age difference = Grandmother's age - Mother's age - Ira's mother is X times younger than her grandmother = Age difference / Grandmother's age

Let's calculate the values:

1. Ira's age: - Grandmother's age = 84 years - Ira's age = 84 / 21 = 4 years 2. Ira's mother's age: - Grandmother's age = 84 years - Mother's age = 42 years - Age difference = 84 - 42 = 42 years - Ira's mother is X times younger than her grandmother = 42 / 84 = 0.5 times

Answer

Based on the given information, Ira is 4 years old, and her mother is 0.5 times younger than her grandmother.
