Explanation:
%DV label= 27% 
1 cup of cooked collared greens= aprx 266.60 mg of Calcium
Assuming Clara is... 
- a teen, her required adequate intake (RAI)=  1300 mg/ day
- an adult, her RAI= 1000 mg/day
For teenaged Clara
∵27 % DV= 270mg
% daily Calcium=   = 20.8 ≈ 21%
 = 20.8 ≈ 21%
=0.21 
<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>
Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.
