Do I add or divide?

Ahmad, Barry, And Tara collected some seashells. Ahmad collected 1/6 of the seashells, Barry collected 1/2 of the seashells, and the rest were collected by Tara. Tara collected 76 seashells. How many seashells did they collect in all?

Since you know that Tara collection 1/3 of the total number of shells, you need to determine what number 76 is 1/3 of.
 
The equation can be setup like this
 
Total / 3 = 76
Total = 76 * 3
Total = 228
