16 is 20% of what number?

Answers

Answer 1
80 because 16 divided by 20%
of means multiply but in this case divide

Answer 2
Set up a proportion first using this formula: 
number/100 = is/of (they are set up like fractions) 

Plug corresponding values into equation: 
20/100 = 16/x (or whatever variable you choose) 

Cross multiply the values: 
20 * x and 100 *16

Set the resulting products equal to each other: 
20x=1600

Isolate the variable by dividing the value in front of it by both sides: 
20x/20 and 1600/20 

Set the variable equal to the resulting value: 
x=80

Check answer by plugging the solution into the original equation: 
20/100 = 16/80

Determine if the values of each side are equal to each other. If so, the solution is correct: 
0.2=0.2

Solution is correct!

16 is 20% of 80 

Hope this helps :)

Kayla packs 4 boxes that weigh 1/6 pound altogether. What does each box weigh

Answers

4 boxes = 1/6 of a pound
If each box weighs the same then you should divide 1/6 of a pound by four. That should give you the weight of each box.

Step One:
1/6÷4= ?

Step Two:
Change the four to a fraction

1/6÷4/1= ?

Step 3:
Use the Keep/Flip/Change rule to rewrite the problem to an easier one.
1/6(Keep)÷4/1= ?
1/6÷1/4(Flip)= ?
1/6×(Change)1/4= ?

Now you have this equation:
1 1
-- × -- = ?
6 4

Step 4:
Multiply across.

1 1 1
--- × --- = ---
6 4 24

Step 5:
Write it out.
Now you have your answer and should write it in C.S.R.Q. format. (Complete Sentence that Restates the Question)

Each box Kayla packed weighs 1/24 of a pound.

The easiest way for me to solve this would be to simply multiply 1/6 by 4 and I got 4/24

4. Stephen wrote the problem 46.8 divided by 0.5. What is the correct quotient?

Answers

Final answer:

To find the quotient of 46.8 divided by 0.5, we use long division. The correct quotient is 136.

Explanation:

To solve the division problem 46.8 divided by 0.5, we can use long division. Here are the steps:

Divide 46.8 by 0.5 to get the quotient. Since 0.5 is smaller than 46.8, we start dividing.We divide 4 by 0.5 to get 8. Since 8 is smaller than 46, we bring down the next digit, which is 6.We divide 46 by 0.5 to get 92. Since 92 is smaller than 68, we bring down the next digit, which is 8.We divide 68 by 0.5 to get 136.

The correct quotient is 136.

Final answer:

The correct quotient when dividing 46.8 by 0.5 is 93.6, since dividing by 0.5 is equivalent to multiplying by the reciprocal, which is 2.

Explanation:

The student's question is about finding the result of the division 46.8 divided by 0.5. To find the correct quotient, follow these steps:

Understand that dividing by 0.5 is the same as multiplying by 2 because 0.5 is equivalent to 1/2, and the reciprocal of 1/2 is 2.Multiply 46.8 by 2 to find the quotient.The result is 93.6.

Therefore, the correct quotient when 46.8 is divided by 0.5 is 93.6. Recognizing the reciprocal relationship, dividing by 0.5 is equivalent to multiplying by 2. By implementing this understanding and multiplying 46.8 by 2, the correct quotient is determined to be 93.6. This approach clarifies the process involved in dividing by fractions and offers a clear solution to the student's question.

The United States uses 24℅ of the world's supply energy What fraction of the world's energy is this ?

Answers

So, the US uses 24% of 100% of the world's energy. As a fraction this is = 7/25

The United States uses 24% of the world's energy supply, and this percentage as a fraction is 24/100, which simplifies to 6/25.

The United States uses 24% of the world's energy supply. To convert this percentage to a fraction, we take the percentage and write it over 100. So 24% becomes 24/100. This fraction can then be reduced to its simplest form by dividing both the numerator and the denominator by their greatest common divisor, which is 4 in this case. Therefore, 24/100 simplifies to 6/25.

To reiterate, the fraction that represents the U.S. consumption of the world's energy supply is 6/25.

A. k = 11.9 → 11.9 > 12 FALSE

B. k = 12.1 → 12.1 > 12 TRUE

C. k = 13.0 → 13.0 > 12 TRUE

D. k = 19.9 → 19.9 > 12 TRUE

E. k = 10.2 → 10.2 > 12 FALSE

Answer:

Option B , C and D are correct.

The values of k are 12.1 , 13.0 and 19.9

Step-by-step explanation:

Given the inequality: [tex]k > 12[/tex].

The boundary point is not included when the inequality is less than '<' or greater than '>', and is represented by an open circle on the boundary point.

Also, the arrow goes to the right when the inequality symbol is greater than (>) or greater than equal [tex]\geq[/tex].

since, the inequality  [tex]k > 12[/tex] as shown in figure below;

The solution of k which satisfy k > 12 are;

12.1 , 13.0 and 19.9 .
