1.628 &gt; 1.63<br><br><br>I don’t understand math I’m sorry-
Lina20 [59]

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

<u>1</u>.628

<u>1</u>.630

the first digit is the same. Both of these numbers are also before the decimal.

let's look at the second digit.

1.<u>6</u>28

1.<u>6</u>30

they are also the same. Both of these are also right after the decimal point.

now let's look at the third digit.

1.6<u>2</u>8

1.6<u>3</u>0

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
