If Barry has 120 stamps and Bob has 3/5 as many stamps as Barry, you can set up the proportion:

3/5 = x/120

Where x is the number of stamps Bob has. To solve for x, you can cross-multiply:

3 * 120 = 5 * x

Simplifying:

360 = 5x

x = 72

So, Bob has 72 stamps. To find out how many more stamps Barry has than Bob, you can subtract the number of stamps Bob has from the number of stamps Barry has:

120 - 72 = 48

Barry has 48 more stamps than Bob.
