Write an expression for 40% of 25
2 answers:
For this case we must find an expression to find 40% of 25. So, we make a rule of three:
25 -----------> 100%
x -------------> 40%
Where "x" represents the amount that determines 40% of 25.
40% of 25 is 10. And an expression to find it is:
Answer:
<u>Answer:</u>
* 25
<u>Step-by-step explanation:</u>
We are asked to find an expression for 40% of 25.
Per-cent, as the name suggests, means one part in every hundred. To find 40%, we will divide the number 40 by 100. While the word 'of', in the mathematical context, means to multiply.
So the expression for 40% of 25 will be:
* 25

To solve this problem, we have to use the area of both gauze or the dimensions on each gauze and compare them. we can see that the sheets are not similar as they have different areas.
<h3>Area of Rectangle</h3>The area of a rectangle is given as the product between the length and it's width.
Data;
- Length = 9in
- Area = 45in^2
- width = ?
- length 2 = 4in
- width 2 = 3in
In the first gauze, the area is given as 45in^2 and we have value of the length. To find the width of the first gauze can be calculated as
We can see that the width are not equal so is their length.
But if we would truly compare them, the accurate way to do that is by their area
The area of the second gauze is given by
From the above calculations, we can see that the sheets are not similar as they have different areas.
