It is not always the same. In many countries, the smallest unit of money is 0.01 (hundredth), so money is almost always rounded to two decimals. But this may vary from country to country. Some may use more or less decimals - or not use decimals at all.
There are infinitely many of them. 0.3011, 0.30111, 0.3011111111, 0.30151 are 4 examples.
All of them from 0.0450 to 0.0549 . That's 99 of them, but I think 98 is a better answer, because 0.0500 wouldn't need to be rounded at all.

You go backwards in decimals three times. Answer = 300 milligrams.
1. When adding, the decimals MUST line up: 012.3 +32.1 2. When multiplying, you dont have to put the decimals side by side: 12.3 x323.55 Then you count how many numbers are after the decimals, which, in this case, is three. Hope it helped!
