Final answer:
To calculate a fraction in its lowest terms, we can use prime factorization. By dividing both the numerator and the denominator of the fraction by their greatest common divisor, we can simplify the fraction to its lowest terms.
Step-by-step explanation:
The subject of this question is Mathematics and the grade level is High School.
To calculate a fraction in its lowest terms, we can use prime factorization. Prime factorization involves finding the prime numbers that divide a number without leaving a remainder. By dividing both the numerator and the denominator of the fraction by their greatest common divisor, we can simplify the fraction to its lowest terms.
For example, if we have the fraction 12/18, we can find the prime factors of 12 (2 * 2 * 3) and divide both the numerator and denominator by their greatest common divisor, which is 6. This simplifies the fraction to 2/3.
