When I run the query:

```
select (100/50)

```

It give me 2 - good.

But when I run the query:

```
select (50/100)

```

I was expected it will give me 0.5... but it gives me 0 instead? Why? and How can I get the 0.5?

```
select (25/(30))*100

```

I was expected it will give me 83.33 but it also gives 0 instead?
