A tank receives 1 1/3 gallons in the morning and 2 5/6 gallons in the afternoon. How much was added in total?

Correct answer to question 59 (Arithmetic Reasoning): 4 1/6 gallons

Method

Convert to sixths: 1/3 becomes 2/6, so the fractions give 2/6 + 5/6 = 7/6, which is 1 1/6. Adding that to the 3 whole gallons gives 4 1/6.
