Question

Doctors treat 380 children of those 15 percent had broken collar bones. What number of kids had broken collar bones?

Answer 1

  Part%            Part Quantity

-------------  =  --------------------

Whole %        Whole Quantity

• Part % = 15%
• Whole % = 100%
• Part Quantity = Number of children with broken collar bones = x
• Whole quantity = 380 children

 

 15%           x children

--------  =  ------------------

100%        380 children

 

Multiply both sides by 380:

 

(15/100)*380 = x

 

Solve for x.
