Answer:
31.01, 180.8, 0.2, 15501
Step-by-step explanation:
Puzzle 1:
The first rule takes out 301
The second rule has to have a 1 in the units place so that takes out 3.1, 3.101, and 30.1
The 3rd rule takes out 1.01, and 1.03
Rule 4, is self explanatory, so it takes out 31.3
and the last rule takes out 31.1 bc there is no hundredths column
That leaves you with 31.01
Puzzle 2:
Rule 1 takes out 18180
Rule 2, self explanatory, takes out 180
Rule 3 takes out numbers less than 18 so 1.81 and 0.18
Rule 4 takes out 18.01, 1800, 188, and 18.8
That leaves you with 180.8
Puzzle 3:
Rule 1 takes out 0.24, 0.5, and 2.02
Rule 2 takes out 0.15
Rule 3 takes out 0.02, 0.01 and 0.1 (bc it just says greater than and not equal to so it takes this one out)
Rule 4 takes out 0.12
That leaves you with 0.2
Puzzle 4:
Rule 1 takes out 45000
Rule 2 takes out 5401, 5444, and 4544
Rule 3 takes out 5454
Rule 4 does not take out any because all the remaining numbers ( 14500, 15501, 14534, and 10500) have 5 hundreds
Rule 5 takes out 14500, 14534, and 10500
That leaves you with 15501
Hope this helped :)
