Answer:
the recommended number of caories for a 11 year old male = 220.
Step-by-step explanation:
it is given that frank consumes 660 calories during breakfast.
660 calories is the 30 percent of recommended calories for a day.
let the number of calories required for a day be x.
therefore 30 percent of x = 660
therefore 
×x = 660
30x= 660×100
x=660×
x= 
×660
x= 2200
solving the equation we get x= 2200
there the recommended number of caories for a 11 year old male = 220.
