before you can add any fraction together you first need to make the denominators (the numbers on the bottom) the same.

in this instance the way to do that is to change the denominator of the first number,

95/19 = 475/95
19/95 = 19/95

(now divide all numbers to make the denominators the lowest they possibly can be).

475/95 = 25/5
19/95 = 1/5

25/5 + 1/5 = 26/5
