45 is closer to 50 because in maths when numbers are rounded up or down any digit of 5 or more rounds the number up to the next higher 'ten' while any digit of less than five rounds it down to the next lower 'ten.' Using this rule 45 rounds up to 50 but 55, which also ends in a 5, does not round down to 50 but rounds up to 60.
