Answer:

16 1/15

Step-by-step explanation:

Add the whole numbers. 7+8=15

Now, combine the fractions 2/3 and 2/5. To do so, you need a common denominator. The LCD between 3 and 5 is 15.

Whatever you do to one side you must do to the other.

(5/5) 2/3+ 2/5 (3/3)

10/15+6/15=16/15

15+16/15

16/15 is an improper fraction, so convert this fraction to a mixed number.

16/15= 1 1/15

Finally, add the two together. 15+ 1 1/15=

16 1/15
