Tristan has a 17/24 lb fraction of a pound of grapes now.

Step-by-step explanation:

Given

To determine

What fraction of a pound of grapes does Tristan have now?

In order to get the total fraction of a pound of grapes, all we need is to add the number of grapes Tristan had at home and the number of grapes Tristan had at the store.

i.e.

Current number grapes = 1/3 + 3/8

Least Common Multiple of 3, 8: 24

Adjust fractions based on L.C.M

                                          = 8/24 + 9/24

Apply the fraction rule:  

                                           = (8 + 9) / 24

                                            = 17/24 lb

Therefore, Tristan has a 17/24 lb fraction of a pound of grapes now.
