2.4 -0.01 1/4 12% -.6 from least to greatest​
RUDIKE [14]

Answer:

-.6, -.01, .12, .25, 2.4

Step-by-step explanation:

We can start by putting the fractions and percents into decimals to help simplify the problem.

1/4 is equivalent to .25 and 12% is the same as .12

-.6 and -.01 are first since they are negative

Then .12, .25, and 2.4

-.6, -.01, .12, .25, 2.4
