Answer:
So that's actually not true. When comparing decimals you should compare each digit. Remember adding a 0 at the end does not change the value of the decimal. So lets look at it up and down:
remember line up the decimal to decimal
1.628
1.630
the first digit is the same. Both of these numbers are also before the decimal.
let's look at the second digit.
1.628
1.630
they are also the same. Both of these are also right after the decimal point.
now let's look at the third digit.
1.628
1.630
In this case, the bottom number has a higher value. Since 3>2, the bottom number is the overall biggest. Or you could look at it and say "Oh! 30 is bigger than 28!" I hope this helps you, and if this wasn't what you were looking for, oops
