Christie decided to make bracelets for the fifth grade class girls. Two-fifths of the bracelets were finished on Monday, and 3/7 of the bracelets were finished on Tuesday. What part of the total number of bracelets are finished?
You have to find a common denominator for the fractions. 5 and 7 both go into 35 which is the lowest common multiple of 5 and 7. 2/5 is multiplied by 7/7 and 3/7 is multiplied by 5/5. Then add the two fractions. So 29/35 parts are finished of the total number of bracelets.
