Least to greatest 0.2,4/15,0.21,1/4

Turn all rational numbers into fractions:

0.2 remains as it is

4/15 as a decimal is 0.26 with the 6 repeating

0.21 remains as it is

1/4 as a decimal is 0.25

Now we can organize from least to greatest as shown below:

0.2, 0.21, 0.25 (1/4), 0.2666666 (4/15)

Hope this helped!

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
