\(2\frac{5}{8}-1\frac{1}{4}\)
First, make them into improper fractions.
\(\frac{21}{8}-\frac{5}{4}\)
The least common denominator is 32.
\(4(\frac{21}{8})-8(\frac{5}{4})\)
\(\frac{84}{8}-\frac{40}{4}\)
Simplify.
\(\frac{21}{2}-10\)
\(\frac{21}{2}=10\frac{1}{2}\)
\(10\frac{1}{2}-10=\frac{1}{2}\)
So your answer is 1/2 or 0.5.
