Question

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

Answer 1

Use long division to convert 1230
to a decimal.

Answer 2

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.

Answer 3

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.
