The answer is in the question.  It asks for "miles per gallon".

$\dfrac{miles}{gallon}\longrightarrow\dfrac{253\;miles}{10.07\;gallon} = 25.12\;mpg$

This is he exact answer.  It's really up to you how to "estimate" this.  You MIGHT say, 253 isn't too far from 250.  You MIGHT say, 10.07 isn't too far from 10.  250/10 = 25 and this reproduces the estimate given with no work shown.
