No, Anat is not correct. To simplify fractions you must find the Greatest Common Factor (GCF). The GCF of 20 and 25 is 5. So then we divide both numbers by the GCF. 20 divided by 5 =4 and 25 divided by 5=5. So the simplest form is 4/5.
Anat's simplification of 25 20 as 5 2 is incorrect. The correct simplest form is 5 4 . This is found by dividing both the numerator and denominator by their Greatest Common Factor, which is 5.
