First, you want to add together the numbers in the extended ratio. 6 + 7 + 8 = 21. This helps because you're looking to find how much greater the triangle is than the ratio.
So now, since you have the total "perimeter" of a triangle with sides of that ratio, just divide 63 by 21 to find how many times that ratio fits into this triangle.
63 / 21 = 3
So you now know that if you multiply all the parts of that ratio by 3, it'll get the side lengths of the triangle with a perimeter of 63 feet.
6 * 3 : 7 * 3 : 8 * 3 = 18:21:24
So the side lengths would be 18 feet, 21 feet, and 24 feet.
To check, I would add all the sides together to see if it equals 63 feet:
To solve the problem it is trial and error since we
don’t know how many hotdogs and bottled water was sold. To trim down to
problem, negative values and decimal values are not included because there is
no negative amount and a decimal amount.
