b) 2/11 gal.

To do this problem make both of them have the same denomnator. Try to find the smallest number by seeing the smallest multiple 8 and 3 have in common. This would be 24 since thats the smallest number they have in common. For 1/8 to get 24 in the denominator multiply top and bottom by 3 to get 3/24 For 1/3 to get 24 in the denomnator multiply top and bottom by 8 to get 8/24 We need 24 in both denominators to add them became same denominators allow us to add the numerators 3/24 + 8/24=11/24 since 8+3=11 in the denominator The answer is c
