Divide. Give the exact answer, written as a decimal.

921 ÷ 2.5 =

To solve \( 921 \div 2.5 \), we can multiply both the numerator and the denominator by 10 to eliminate the decimal in the divisor:

\[
\frac{921}{2.5} = \frac{921 \times 10}{2.5 \times 10} = \frac{9210}{25}
\]

Now, perform the division:

\[
9210 \div 25 = 368.4
\]

So, the exact answer is \( 368.4 \).
