-25 15/19 + 9/1

get a common denominator of 19

they multiplied 9/1 * 19/19 = 171/19

-25 15/19 + 171/19 =

change the mixed number to an improper fraction

(19* 25 +15)/19 = 490/19

-490/19 + 171/19 =

add together

-319/19

now convert the improper fraction back to a mixed number

19* 16 =304 319-304=15

-319/19 =-16 15/19
