Question

What is the value of 0.8–0.6? Write your answer as a fraction in lowest terms

Answer 1

Given expression:

• $0.8 - 0.6$

To simplify the expression as a fraction in simplest form, let us multiply both terms by 10. Then, both terms must also be divided by 10.

   $\implies \dfrac{[10(0.8) - 10(0.6)]}{10}$

   $\implies \dfrac{[8 - 6]}{10}$

   $\implies \dfrac{[2]}{10} = \dfrac{2}{10}$

When 2/10 is simplified in lowest terms, we get;

   $\implies \dfrac{2}{10} \implies \dfrac{1 \times 2}{5 \times 2} \implies \dfrac{1}{5}$

Therefore, 0.8 - 0.6 in fraction form is 1/5.
