Since both are negative numbers in this case, we need to find the number closest to zero. But first we need to make sure both the numbers are in the same format. One is in decimal while the other is in fraction form.
-3.5 is also -3 1/2 or -3 2/4
-3 1/4 is also -3.25
seeing how -3 1/4 is closer to zero by .25, that makes it the greater number compared to -3.5
