Answer:
No 1.32 is not greater than 1.456 or 1.321 because if you look at the 4 in 1.(4)56 it is greater than both 1.32 and 1.321 but I know your like what about 1.32 and 1.321 well 1.32 is not greater in anyway and I know you can just add a number behind it but the only number you can add is a zero so therefore 1.32 is not greater.
Explanation:
1.456-for is greater than 3
1.321-3 is not greater than 3 because it is the same
1.32-3 is not greater than 3 because it is the same
now the 1 is what makes 1.321 greater at the end
