Kiaria Is 7 Years Older Than Jay. Martha Is Twice As Old As Kiaria. The Sum Of Their Three Ages Is 77. Find The Ratio Of Jay's Age To Kiaria's Age To Martha's Age.
Unraveling the Mystery of Their Ages
In this intriguing mathematical puzzle, we are presented with three individuals: Kiaria, Jay, and Martha. The problem states that Kiaria is 7 years older than Jay, Martha is twice as old as Kiaria, and the sum of their three ages is 77. Our task is to find the ratio of Jay's age to Kiaria's age to Martha's age. To solve this enigma, we will employ algebraic techniques and logical reasoning.
Setting Up the Equation
Let's denote Jay's age as J, Kiaria's age as K, and Martha's age as M. We are given the following information:
- Kiaria is 7 years older than Jay: K = J + 7
- Martha is twice as old as Kiaria: M = 2K
- The sum of their three ages is 77: J + K + M = 77
Substituting and Simplifying the Equation
We can substitute the expressions for K and M into the third equation:
J + (J + 7) + 2(J + 7) = 77
Expanding and simplifying the equation, we get:
J + J + 7 + 2J + 14 = 77
Combine like terms:
4J + 21 = 77
Subtract 21 from both sides:
4J = 56
Divide both sides by 4:
J = 14
Finding Kiaria's and Martha's Ages
Now that we have found Jay's age, we can use the first equation to find Kiaria's age:
K = J + 7 K = 14 + 7 K = 21
Next, we can use the second equation to find Martha's age:
M = 2K M = 2(21) M = 42
Calculating the Ratio of Their Ages
Now that we have found the ages of Jay, Kiaria, and Martha, we can calculate the ratio of their ages:
Ratio = J : K : M Ratio = 14 : 21 : 42
To simplify the ratio, we can divide all the numbers by their greatest common divisor, which is 7:
Ratio = 2 : 3 : 6
Conclusion
In this mathematical puzzle, we have successfully unraveled the mystery of Kiaria, Jay, and Martha's ages. By using algebraic techniques and logical reasoning, we have found the ratio of their ages to be 2:3:6. This problem serves as a reminder of the importance of careful analysis and problem-solving skills in mathematics.
Additional Insights
