Write fractions in lowest terms
Key notes:
A fraction is written in lowest terms when it uses the smallest possible numerator and denominator.
To put a fraction in lowest terms, find the largest number that divides both the numerator and the denominator. Divide both the numerator and the denominator by that number.
Learn with an example
🔥Write 5/8 in lowest terms.
Find the largest number that divides both the numerator and the denominator. The largest number that divides both 5 and 8 is 1. This fraction is already written in lowest terms.
🔥Write 4/6 in lowest terms.
Find the largest number that divides both the numerator and the denominator. The largest number that divides both 4 and 6 is 2. Divide the numerator and denominator by 2.
4 ÷ 2 = 2
6 ÷ 2 = 3
4/6 written in lowest terms is 2/3.
🔥Write 3/6 in lowest terms.
Find the largest number that divides both the numerator and the denominator. The largest number that divides both 3 and 6 is 3. Divide the numerator and denominator by 3.
3 ÷ 3 = 1
6 ÷ 3 = 2
3/6 written in lowest terms is 1/2.
