This question is about understanding and applying the concept of equivalent fractions. Equivalent fractions are fractions that have different numerator and denominator but represent the same part of a whole. They can be found by multiplying or dividing the numerator and denominator by the same number. <br /><br />1. For the fraction 1/2, we find equivalent fractions with denominators 4 and 8. We multiply the numerator and denominator of 1/2 by 2 to get 2/4 and by 4 to get 2/8.<br />2. For the fraction 2/4, we find equivalent fractions with denominators 2 and 6. We divide the numerator and denominator of 2/4 by 2 to get 1/2 and by 2 to get 3/6.<br />3. For the fraction 3/9, we find equivalent fractions with denominators 3 and 12. We divide the numerator and denominator of 3/9 by 3 to get 1/3 and by 3 to get 4/12.<br />4. For the fraction 6/9, we find equivalent fractions with denominators 3 and 6. We divide the numerator and denominator of 6/9 by 3 to get 2/3 and by 3 to get 4/6.<br />5. For the fraction 6/12, we find equivalent fractions with denominators 6 and 2. We divide the numerator and denominator of 6/12 by 6 to get 1/2 and by 12 to get 1/2.<br />6. For the fraction 5/10, we find equivalent fractions with denominators 2 and 6. We divide the numerator and denominator of 5/10 by 5 to get 1/2 and by 2 to get 3/6.
