Video Summary

To subtract fractions, find the common denominator of the two fractions, then multiply each fraction by the appropriate form of 1 to get equivalent fractions with the same denominator. Then, subtract the numerators of the two fractions and place the answer over the common denominator. Finally, simplify the fraction if possible. For example, to subtract 3/4 from 5/6, the common denominator is 12. So, we multiply the first fraction by 2/2 and the second fraction by 3/3 to get 6/12 and 15/12. Then, we subtract the numerators to get 9/12. Finally, we simplify the fraction by dividing the numerator and denominator by 3 to get 3/4.
