Write fractions in the lowest terms
Key Notes :
A fraction is written in the lowest terms when it uses the smallest possible numerator and denominator.
To put a fraction in the lowest terms, find the largest number that divides both the numerator and the denominator. Divide both the numerator and the denominator by that number.
Ex:
4/5 = 4/5
10/5 = 2/1
3/9 = 1/3
25/100 = 1/4
6/9 = 2/3
Learn with an example
➡️ Write 3/9 in lowest terms.
_____ / _____
Find the largest number that divides both the numerator and the denominator. The largest number that divides both 3 and 9 is 3. Divide the numerator and denominator by 3.
3 ÷ 3 = 1
9 ÷ 3 = 3
3/9 written in lowest terms is 1/3.
➡️ Write 2/8 in the lowest terms.
____ / ____
Find the largest number that divides both the numerator and the denominator. The largest number that divides both 2 and 8 is 2. Divide the numerator and denominator by 2.
2 ÷ 2 = 1
8 ÷ 2 = 4
2/8 written in lowest terms is 1/4.
➡️ Write 1/3 in the lowest terms.
_____ /____
Find the largest number that divides both the numerator and the denominator. The largest number that divides both 1 and 3 is 1. This fraction is already written in the lowest terms.
