Order the numbers from greatest to least:17,601;20,007;17,610

You can use place value to order decimals.
To put these numbers in order, first determine which is the least number.
Compare the ones place. They are all the same.
Compare the tenths place. 0.35 and 0.3 both have 3 in the tenths place.
Compare the hundredths place. 0.3 can also be written as 0.30.
0 ! 5 so 0.3 ! 0.35.
The numbers in order from least to greatest are 0.3, 0.35 and 0.55.
You can also use a number line to put the numbers in order.
The numbers become greater as you move to the right on the number line.
Therefore, since 0.55 is the farthest to the right, it is the greatest number.
0.35 is to the right of 0.3, so it is greater than 0.3.
The decimals in order from least to greatest are 0.3, 0.35, and 0.55.

642.
They are all even numbers and they are all in order from greatest to lease. Their sum must add up to 12 also. so 6 +4 +2 = 12.
If you round it to the nearest 1000 you get 642.
Take each thing they are saying as 1 of your rules to get the number. And use that to eliminate numbers for example. 1 3 5 7 are all eliminated. then use numbers to get to 12 that must be even. Finally make sure they are from greatest to least.

enter a;
enter b;
enter c;
if a>=b and a>c
print "a is the greatest number"
then if b>=a and b>c
print "b is the greatest number"
then if a=b and a=c
print "a, b, c are equal"
if not print "c is the greatest number"

this is pseudocode.. or my drunken attempt to remember pseudocode... but I think the logic could work.
