In order to decide if the given fractions are equivalent, we first need to write each fraction in lowest-terms. Remember, a fraction is written in lowest terms if the greatest common factor of the numerator and denominator is 1. For our first fraction, the greatest common factor of 4 and 10 is 2, we must divide both the numerator and the denominator by 2. Once we have done this, we will get the equivalent fraction 2/5. Next, let’s look at our second fraction. Since the greatest common factor of 2 and 6 is 2, we must divided both the numerator and the denominator by 2 to get the equivalent fraction 1/3. These fraction are not equivalent because they do not have the same value.
