To find the difference between two numbers, use subtraction. Subtract the smaller number from the larger number.
In this case, that would be 1 minus 3/8. To make it easy, we can change the 1 into a fraction so that it matches 3/8. Since 1 is a whole number, you can divide it into eighths and have 8 of them, or 8/8.
Now we can subtract 8/8 minus 3/8. Since the denominator is the same, we can put them together as (8-3)/8.
8-3 is 5, so the answer is 5/8.
1 inch is 5/8 inch longer than 3/8 inch.
