To find out how many pencils Frank has, we can use the information provided.
We know the total number of pencils: \[ \text{Total pencils} = 14 \]
We also know how many pencils James and Ann have: \[ \text{James' pencils} = 2 \] \[ \text{Ann's pencils} = 4 \]
Now we can calculate how many pencils James and Ann have together: \[ \text{Total pencils (James + Ann)} = \text{James' pencils} + \text{Ann's pencils} = 2 + 4 = 6 \]
Now, we can find out how many pencils Frank has by subtracting the number of pencils that James and Ann have from the total number of pencils: \[ \text{Frank's pencils} = \text{Total pencils} - \text{Total pencils (James + Ann)} = 14 - 6 = 8 \]
Thus, Frank has 8 pencils.
