5.29 is less than 52.9
look at where the decimal point is at. To the left of it is the whole number, and to the right of it is decimal. If one of the whole numbers is greater than the other, than you have your answer. If it is after the decimal point, the number that is larger towards the left (closest to the decimal point) will make that number larger than the other
hope this helps
