One gallon of cleaning solution requires 6 oz of ammonia. If the maintenance department needs 230 gallons of solution to clean all of the floors, how much ammonia is needed?

A. 1380 gallons

B. 6900 gallons

C. 1380 oz

D. 1400 oz

Answer Explanation:

from the given data, one gallon of cleaning solution requires 6 oz of ammonia. The mathematical expression of this statement can be expressed in two ways:

           

Or

               

The question requires we find the amount of ammonia needed to make 230 gallons of the solution. So, we use the second option and proceed as follows:

                   

From the above equation, gallon of solution will cancel, and oz of ammonia is left.

Therefore, the solution will require 1380 oz of ammonia.

Therefore, the Correct Answer is C.

  • Q #1: How may milliliters are there in 3.2 liters?  

    A. 0.32

    B. 32

    C. 3200

    D. 320

    Answer Explanation

    We know that 1 L =1000 mL, which we use to convert between the two units. The conversion fractions of interconverting are:

    And

    Since we want to end up with millimeters, the second conversion is used in converting L to mL as:

    Thus, 3.2 L is equivalent to 3200 mL.

  • Q #2: Three friends are sharing a burger. One friend eats a quarter of the burger. The other two friends equally divide the rest among themselves. What portion of the burger did each of the other two friends receive?  

    A. 1/6

    B. 1/4

    C. 3/4

    D. 3/8

    Answer Explanation

    : we are needed to find the portion of burger the two other friends share between themselves. A whole burger is 1, and we know that,

    One friend=1/4 of 1=1/4*1=1/4

    Remaining amount=1-1/4=4/4-1/4=3/4

    Thus, ¾ of burger is left for two friends to share among themselves. Then, each friend will get

    So, the other two friends will each get 3/8 of the burger.
