First of all, let's take a look on the question.

Here, 0 is added to 15 and the resultant is 15 only. So, we can say that 0 when added with any number gives the same number as the resultant.
So, the property is known as <u>Identi</u><u>ty</u> property because 0 is added to get the identity of the same number.
<u>The Correct Option:</u>

So, let's know more...
- Commutative property ➝ a + b = b + a
- Associative property ➝ a + (b + c) = (a + b) + c
- Distributive property ➝ a(b + c) = ab + ac
So this is the general form of these properties which is general observed in the rational numbers.

No. of people don't like to be teacher
= 100% - 75% = 25%
<h3>

</h3>
So, 15 number of students doesn't like to be teacher
If you want to increase something by 3%, you would ADD 100% to it, so:
3% + 100% = 103%
Then you divide it by 100 to turn it into a decimal, so:
103% / 100 = 1.03
So to increase by 3%, the multiplier would be 1.03
If you wanted to decrease by 3%, you would SUBTRACT 100% from 3%, so:
100% - 3% = 97%
And then you would divide 97% by 100 to turn it into a decimal (multiplier), so:
97% / 100 = 0.97
So to decrease by 3%, the multiplier would be 0.97
STEP-BY-STEP SOLUTION:
Let's solve this problem step-by-step.
As posters are generally rectangular in shape, we will establish the formula for the area of a rectangle which we will be using as displayed below:
Area = height × width
Now let's find the area of the postwr using the above formula.
Height = 2 feet
Width = 0.7 feet
Area = height × width
Area = 2 × 0.7
Area = 1.4 square feet
ANSWER:
Therefore, the answer is:
The area of the poster is 1.4 square feet.
