Question

write 5.5 as a simplified mixed number.

Explanation:

Identify the whole number and decimal parts

$$ 5.5 = 5 + 0.5 $$

Convert the decimal part to a fraction

$$ 0.5 = \frac{5}{10} $$

Simplify the fraction and write as a mixed number

$$ \frac{5}{10} = \frac{5 \div 5}{10 \div 5} = \frac{1}{2} \implies 5\frac{1}{2} $$

Answer:

\(5\frac{1}{2}\)
