What is 0.80 converted to a fraction? The answer should be given in simplest form.

To convert 0.80 to a fraction, we can write it as 80/100, since the decimal represents hundredths. To simplify the fraction, we can divide both the numerator and denominator by the greatest common divisor, which is 20. Therefore, 0.80 can be written as 4/5 in simplest form.

Use long division to convert 1230

to a decimal.

To convert 1230 to a decimal using long division, we divide 1230 by 10:

```
________
10 | 1230
```

First, we divide 10 into 12, which gives us 1. We write this above the line:

```
________
10 | 1230
- 10
---------
2
```

Next, we bring down the next digit, which is 3, and divide 10 into 23. This gives us 2.

```
________
10 | 1230
- 10
---------
20
- 20
---------
3
```

Finally, we bring down the last digit, which is 0, and divide 10 into 30. This gives us 3.

```
________
10 | 1230
- 10
---------
20
- 20
---------
30
- 30
---------
0
```

Since there is no remainder and no more digits to bring down, the division is complete. Therefore, 1230 converted to a decimal is 123.0.

To convert 0.80 to a fraction, we can follow these steps:

Step 1: Write down the decimal as a fraction by placing the decimal number over 1 followed by the appropriate number of zeros.

0.80 = 0.80/1

Step 2: Remove the decimal by multiplying the numerator and denominator by a power of 10 that will eliminate the decimal.

0.80/1 = 80/100

Step 3: Simplify the fraction by dividing the numerator and denominator by their greatest common factor.

The greatest common factor of 80 and 100 is 20.

80/100 รท 20/20 = 4/5

Therefore, 0.80 is equal to 4/5 in simplest form.
