Answer ASAP/. What is 2 1/2 and 2.4 and 2.35 and 2 1/8 listed and greatest to least// I need the answer ASAP
crimeas [40]
Since 1/2=0.5 and 1/8=0.125, we have 2.5, 2.4, 2.35, and 2.125. The first number we look for is the one to the left, and they're all the same, so that doesn't necessarily help. Next, we have a 5, 4, 3, and 1. They're already in order from greatest to least, so that's awesome!
