The video tutorial explains how to determine if a fraction is in its simplest form by checking if the only common factor between the numerator and denominator is one. It provides examples of simplifying fractions like 8/12 and 4/6 by dividing both parts by their greatest common factor. The tutorial concludes with confirming that 2/3 is already in its simplest form as it has no common factors other than one.

What is the condition for a fraction to be considered in its simplest form?

• When both the numerator and denominator are even numbers

• When the numerator is larger than the denominator

• When the fraction is a proper fraction

• When the only common factor between the numerator and denominator is one

Why is the fraction eight over twelve not in its simplest form?

• Because eight is an even number

• Because there are common factors between eight and twelve other than one

• Because eight is less than twelve

How can you simplify the fraction eight over twelve?

• By subtracting one from both the numerator and denominator

• By dividing both the numerator and denominator by their greatest common factor

• By adding one to both the numerator and denominator

• By multiplying both the numerator and denominator by two
