they are both equal since 0.4 is just 0.40 without a 0 because you can add as many 0 at the end of a decimal but it still won't matter. For example 0.5000 would just be 0.5 because those 0 don't mater. if the 0 is in the middle of a decimal like 0.709 than the 0 between the 7 and 9 would matter because there is a number after it
