Question

Show that 0,75 is a rational number​

Answer 1

Explanation:

A decimal is by definition a number between two whole numbers. Specifically, the decimal 0.75 is between 0 and 1. It is a fraction of the number 1. We have that:

`0.75=(0.75)/(1.00)=75/100`

We can reduce the fraction by dividing the top and bottom by 25 to get:

`75/100=3/4`

The correct way to prove 3/4 is rational would probably be to do long division, to see how many times 4 goes into 3. You would get 0.75 times which is rational
