Answer:
I believe the correct answer is C
Step-by-step explanation:
if you convert 1/5 into a decimal it would be 0.2
if you convert 1/21 to a decimal it would be 0.4 then you make it a square root it would be 0.6
4.15 is already a decimal so you don't have to do anything to it.
if you turn 21 into a square root the would be 4.5
so if you line all the numbers up from smalllest to lagerst it would look like this
1/5,1/21,21,4.15
so c is the corrcet answer
