Take both mixed numbers (a whole number plus a fraction) and turn them into improper fractions ( a numerator (top number) bigger than the denominator (bottom number). To do this, multiply the denominator by the whole number, and add the result to the numerator.
5 5/8 will become 45/8
1 1/2 will become 3/2.
Area is length* width, so width would be Area/ length. So 45/8 is the area and 3/2 is the length. Now you have (45/8)/(3/2). To divide fractions, take the second fraction and flip the numerator and denominator, forming the reciprocal (2/3). Now multiply 45/8 and 2/3
The result is 90/24, and simplifying would get 15/4, or 3 3/4. This is the width(or length)
$440.34 because 27 1/4 X 5.15 = $440.3375 rounded to nearest hundredth $440.34
4 because it is b I looked we will get it done together
Using proportions, the algebraic expression for the cost of the 24 ads with the discount is:
Cost = 21.12c.
In which c is the cost of a single add.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, if more than 10 ads are posted, the cost C of each job is discounted by 12%, that is, it is of 88% of C. Hence, the algebraic expression for the cost of the 24 ads with the discount is:
C = 24 x 0.88 x c = 21.12c
In which c is the cost of a single add.
