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.
Answer: A standard equation is set up like this: Ax + By = C (where A, B, and C represent numbers). To find the slope (or the rate at which something changes) you must divide the value of A by the value of B (A / B).
