-0.05 is larger. Since they're negative, you're going by which is closer to 0 rather than farther. -0.05 is closer to 0 on a number line, so it's larger than -0.25.
-0.05 is larger if u r confused between these stuff u can use a number line and get the numbers from the number line and the one that is at the far right is the larger, and the number that at the far left is the smaller.
