<em><u>Question:</u></em>
One dollar is worth 3 1/2 kruneros. What is the value of 43 3/4 kruneros?
<em><u>Answer:</u></em>
The value of
kruneros is 12.5 dollars
<em><u>Solution:</u></em>
Given that,
Dollar is worth three and 3 1/2 kruneros
Which means,
![1 \text{ dollar } = 3\frac{1}{2} \text{ kruneros }\\\\1 \text{ dollar } = 3.5 \text{ kruneros }](https://tex.z-dn.net/?f=1%20%5Ctext%7B%20dollar%20%7D%20%3D%203%5Cfrac%7B1%7D%7B2%7D%20%5Ctext%7B%20kruneros%20%7D%5C%5C%5C%5C1%20%5Ctext%7B%20dollar%20%7D%20%3D%203.5%20%5Ctext%7B%20kruneros%20%7D)
We have to find the value of
kruneros
Let us convert the mixed fractions to improper fractions
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator.
![43\frac{3}{4} = \frac{43 \times 4 + 3}{4} = \frac{175}{4} = 43.75](https://tex.z-dn.net/?f=43%5Cfrac%7B3%7D%7B4%7D%20%3D%20%5Cfrac%7B43%20%5Ctimes%204%20%2B%203%7D%7B4%7D%20%3D%20%5Cfrac%7B175%7D%7B4%7D%20%3D%2043.75)
So we have to find the value of 43.75 kruneros
Let "x" be the value of 43.75 kruneros
Then,
1 dollar = 3.5 kruneros
x dollar = 43.75 kruneros
This forms a proportion and we can solve the sum by cross multiply
![1 \times 43.75 = x \times 3.5\\\\x = \frac{43.75}{3.5}\\\\x = 12.5](https://tex.z-dn.net/?f=1%20%5Ctimes%2043.75%20%3D%20x%20%5Ctimes%203.5%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B43.75%7D%7B3.5%7D%5C%5C%5C%5Cx%20%3D%2012.5)
Thus value of
kruneros is 12.5 dollars
The answer is 48.
A= Hight x Width
Multiply 12 x 4 and you will get 48.
Answer:
Step-by-step explanation:
There is no greatest perimeter. The longer and skinnier you make the rectangle,
the greater its perimeter will become, while the area remains the same.
Example:
6-ft by 6.5-ft .. . . area = 39 sq ft, perimeter = 25 ft
3-ft by 13-ft . . . . area = 39 sq ft, perimeter = 32 ft
1-ft by 39-ft . . . . area = 39 sq ft, perimeter = 80 ft
0.1-ft by 390-ft . . area = 39 sq ft, perimeter = 780.2 ft.
No matter how great the perimeter of the rectangle is, it can always be made
greater, while keeping the same area.
