1.23 is larger than 1.2.

Explanation:

You see, however many zeroes you add to a number after the decimal, the number is still the number.

1.20 is the same as 1.2

1.2000.... is the same as 1.2

You see, for a proper comparison that is easy to compare by just looking at, we just add one zero to 1.2.

So then there are two decimal places for both of the numbers. The second decimal place is the hundreds place.

1.20
1.23

20 is less than 23. Therefore, 1.23 is greater than 1.2!

1.23>1.2

I hope you understand! :D
