Another Problem 1

Question:

(a)
33.101 cm is 51.1% of what amount?
(b)
18.2 in is what percent of 10.1 ft?
(c)
What is 5.4% of 80.0045 kg?



Solution: (a) 64.8 cm, (b) 15.0%, (c) 4.3 kg


Sketch:

Translating each into math (after converting inches to feet!) gives:

(a)
  33.101 = .511 * x  
   64.77698 = x     

(b)
1.5166667 = x * 10.1
  .15016502 = x     
                    
(c)
x = .054 * 80.0045  
  x = 4.320243      

So the answers are: (a) 64.8 cm, (b) 15.0%, (c) 4.3 kg
