Johnny and elizabeth were playing a video game and trying to get all the treasure. johnny got 1/3 of a treasure and elizabeth got 5/9 of the treasure

1/3 + 5/9 =

need to find common denominator (3 & 9)

since 3 goes into 9 9 will be the common denominator so need to change 1/3 t0 3/9 (multiply both numbers by 3)

now you have 3/9 + 5/9 = 8/9 of the treasure has been found

Elizabeth has found more than Johnny

there is 1/9 left to be found
