1 2/3 + 4 7/15... First - covert both fractions to the same denominator...
2/3 = 10/15 the 7/15 fraction doesn't need converting. Now you have 10+7 which of course is 17/15.
17/15 is 1 2/15 - now add the whole numbers (1+4) from the original problem, and your final answer is 6 2/15
twelve fifteenths or four fifths
First we convert them into similar units, giving us 10 fifteenths and 12 fifteenths. Together that is 22 fifteenths or 1 and 7 fifteenths.
two-thirds
12 fifteenths (sure?)19 fifteenths = 10 fifteenths (2/3) + 9 fifteenths (3/5)
To add two thirds and one fifth, first find a common denominator. The least common denominator of 3 and 5 is 15. Converting the fractions, two thirds becomes ten fifteenths, and one fifth becomes three fifteenths. Therefore, ten fifteenths plus three fifteenths equals thirteen fifteenths, so two thirds plus one fifth is ( \frac{13}{15} ).
4/9 plus 7/15 = 41/45 in its simplest form
four and two thirds (7/3 + 7/3 = 14/3 = 4 2/3)
four thirds plus 6 = 71/3
seven fifteenths
8/15, 8 fifteenths
1 4/5
