Answer:
Step-by-step explanation: To write a fraction in lowest terms, we divide the numerator and the denominator by the greatest common factor of what the numerator is and what the denominator is.
Let's look at an example.
Write the following fraction in lowest terms:

To write 2/8 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 2 and 8.
Since the factors of 2 are 1 and 2 and the factors of 8 are 1, 2, 4, and 8, the greatest common factor of 2 and 8 will be 2.
So we divide the numerator and the denominator of 2/8 by 2.
2 ÷ 2 = 1
8 ÷ 2 = 4
