Jada compared the decimals 2.5 and 2.335 and stated that 2.335 was greater because 355 is greater than 5. Why is she incorrect?

• If you add the placeholder zeros, 2.500 > 2.355.

• She is not comparing the right number; 355 is not a whole number, it is part of the whole number 2.

• 2.5 is first on the number line.

• 2.335 is correct; the decimal with more numbers in front of it is always the greater one.
