A toy store uses 3/16 of its space for trains. Its uses 1/16 of its space for boats. How much more space is used for trains than for boats? Simplify the answer if possible.
To find the difference, we must subtract the fraction of space used for boats from the fraction of space used for trains:
3/16 - 1/16 = 2/16
Since 2/16 simplifies to 1/8, there is 1/8 more space used for trains than for boats. Answer: \boxed{\dfrac{1}{8}}.
