What dose lowest terms mean

Lowest terms basically means that the fraction / mixed number is in simplest form. Which means it can't be divided by anything to get a lower number for both the numerator and denominator because they don't have anymore factors that they share. For example, if I wanted to simplify the fraction, 4/8. I would divide by 4 on both the top and bottom since that is their greatest common factor.

4 ➗ 4=1

8 ➗4=2

1/2 would be the "lowest terms" of 4/8 since 1 and 2 don't have any common factors except 1.

That's the description of a fraction when the numerator and denominator

don't have any common factor except '1'.
