If you also join us at http://www.unicoos.com, it'll be great!!! #seeyouinclass :-) For 6th grade PRIMARY SCHOOL and 1st grade SECONDARY SCHOOL, the second of three videos dedicated to adding and subtracting fractions, this time with different denominators. The first thing we'll do is convert all the fractions to a common denominator, using the CROSS PRODUCT method. We'll finish the two examples by obtaining the IRREDUCIBLE FRACTION of each of the fractions obtained.
