Express 2.5 as a fraction in it is lowest form

1 answer

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