Question

Convert 0.8 to a rational number.

Answer 1

To convert 0.8 to a rational number, we need to express it as a fraction.

We can start by writing 0.8 as 8/10.

Then, we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which in this case is 2.
8 ÷ 2 = 4
10 ÷ 2 = 5

So, 0.8 as a rational number is 4/5.
