Three Friends went to the sub shop for lunch. They ordered the 3Ft sub made with 1/4 Ham, 1/5 roast beef, 3/8 turkey. The rest of the sub is made up of lettuce, tomato, and onions. What fraction of the sub is made up of lettuce, tomato, and onions ?

1/4 + 1/5 + 3/8 = 10/40 + 8/40 + 15/40 = 33/40
40/40 = 33/40 = 7/40
