negative numbers work the opposite of how positive numbers work. Think about it like this. -12 is 12 units less than 0 and -12.5 is 12.5 units less than 0 which means that -12.5 is less than -12
no because the bigger the negative the smaller the parts are... so therefore is would be smaller than -12 because its -0.5 smaller the negative sign makes all the bigger numbers smaller than 1
