Answer:   16

Step-by-step explanation:

Let the number be 'g'.

Based on the question, we can write an equation:

    ³/₈ g  -  1  = 5             [add 1 to both sides]

         ³/₈ g   =  5 + 1       [multiply both sides by 8]

           3 g   =  (6) (8)     [divide both sides by 3]

              g   =  48 ÷ 3    [simplify]

              g   =  16

         ∴ the number is 16
