Answer 1

[AI-generated answer — Bot GPT 3.5]

To convert 12.8 to a fraction, we can write it as:

12.8 = 12 + 0.8

Since 0.8 is equivalent to 8/10 or 4/5 in fraction form, we can rewrite the expression as:

12.8 = 12 + 4/5

Now, we can find a common denominator for 12 and 4/5, which is 5. We can rewrite 12 as a fraction with a denominator of 5:

12 = 12/1

Now, we can add the fractions:

12/1 + 4/5 = (12 * 5 + 4)/5 = 60/5 + 4/5 = 64/5

So, 12.8 as a fraction in simplest form is 64/5.

To convert 12.8 to a fraction, we can follow these steps:

Step 1: Rewrite the decimal number as a fraction by placing it over a power of 10.
12.8 can be written as 12.8/1.

Step 2: Multiply both the numerator and denominator by 10 or 100 (depending on the number of decimal places) to remove the decimal.

12.8/1 can be multiplied by 10/10, which gives us 128/10.

Step 3: Simplify the fraction by finding the greatest common divisor (GCD) and dividing both the numerator and the denominator by it.

The GCD of 128 and 10 is 2. Dividing both 128 and 10 by 2 gives us 64/5.

So, 12.8 can be expressed as 64/5 in its simplest form.
