4n - 2n = 2n

Use braces and digits to indicate the set of whole numbers
Sergeeva-Olga [200]

Whole numbers are numbers without decimal points greater than 0.

The set of whole numbers is:

W =\{0,1,2,3,4.....\}

In the introductory part of this solution, I stated that:

  • Whole numbers do not have decimal point
  • The smallest whole number is 0

This means that the following numbers are whole numbers:

1, 9, 10, 67

While the following numbers are not:

-1, 9.0, 1.0, -67

Let W be the set of whole numbers; the set is:

W =\{0,1,2,3,4.....\}

The dots after 4 means the set still continues

Erica says that 1/5 of the national flag of Thailand shown on the right is blue. what’s wrong?
Angelina_Jolie [31]

Answer:

The blue portion of the flag is actually 2/6 or 1/3 of the flag

Step-by-step explanation:

If you look at the size of the blue portion of the line it takes up twice the space as the white part. Imagine a small line drawn through the middle of the blue rectangle, now you can see that the flag is split up into 6 parts, rather then 5! Since we now have 2/6 of the flag being taken up by blue, that can be reduced down to 1/3 of the flag covered in blue.

Iteru [2.4K]

Answer:1 and 1/4


Step-by-step explanation:

Okay, let's see the given: 20/16

So, we can take out 16 from the top to make it 1  4/16

Now, we can simplify that by dividing the top and bottom by 2: 1  2/8

We can simplify that again to get 1 1/4

So the answer is 1 and 1/4
