Subject: Decimals, even numbers, fractions, and order

I have a few questions actually.

How would you explain to children the following:

*Even numbers always end in 2, 4, 6, 8, and 0.

*You can decide which of two fractions is greater by finding equivalent
fractions with the same numerator and comparing them.

*You can stick zeroes at the end of a decimal amount and not change its
value, ex, 3.45 = 3.45000000.

*You can add the same amount to both numbers when your subtracting them and
not change the answer.

*You can halve one number and double another when you multiply and not
change the answer.
