Answer :
5.1 is greater than 5.01 because .1= .10 and .10 is better than .01
5.1 would be the greater amount. look at the place next the whole number. notice that in 5.1 the # next to the whole # is 1. and in 5.01 the # next to the whole # is 0. so ask yourself which is greater: 1 or 0. 1 is greater so the answer would be 5.1
