Question

In a laboratory, a chemist puts fraction numerator 9 over denominator 4 end fraction gallons of liquid in 8 beakers with equal measures. How much liquid is there in one beaker?

  1. fraction numerator 8 over denominator 36 end fraction    
  2. fraction numerator 72 over denominator 4 end fraction    
  3. fraction numerator 9 over denominator 32 end fraction    
  4. fraction numerator 1 over denominator 32 end fraction    

hintHint:

To find the liquid in each beaker, we divide the total liquid amount by the number of beakers to be filled.

The correct answer is: fraction numerator 9 over denominator 32 end fraction


    Total amount of liquid in a laboratory = fraction numerator 9 over denominator 4 end fraction gallons
    Number of beakers to be filled = 8
    Liquid in each beaker = fraction numerator 9 over denominator 4 end fraction divided by 8
    equals fraction numerator 9 over denominator 4 end fraction cross times fraction numerator 1 over denominator 8 end fraction open parentheses text reciprocal of 8 is  end text fraction numerator 1 over denominator 8 end fraction close parentheses
    equals fraction numerator 9 cross times 1 over denominator 4 cross times 8 end fraction equals fraction numerator 9 over denominator 32 end fraction gallons
    Therefore, the liquid in each beaker is 9 over 32 gallons.
