Question

Express 2.5 as a fraction in it is lowest form

Answer 1

To express \( 2.5 \) as a fraction in its lowest form, follow these steps:

1. Write \( 2.5 \) as a fraction:
\[
2.5 = \frac{25}{10} \quad \text{(since 2.5 is the same as } \frac{25}{10} \text{)}
\]

2. Simplify the fraction \( \frac{25}{10} \):
- Find the greatest common divisor (GCD) of 25 and 10, which is 5.
- Divide both the numerator and the denominator by their GCD:
\[
\frac{25 \div 5}{10 \div 5} = \frac{5}{2}
\]

Thus, \( 2.5 \) expressed as a fraction in its lowest form is \( \frac{5}{2} \).
