If 2-1/3 feet of silver ribbon costs $0.14, how much will 9 feet cost?
9 feet of silver ribbon would cost $0.63.
Well, looking at the price, it seems like a great deal for ribbon. Maybe we should all invest in silver ribbon futures! Anyway, to find out how much 9 feet of ribbon will cost, let's do a little math. If 2 and one-third feet cost $0.14, then we can figure out the cost per foot. 2 and one-third feet is also known as 7/3 feet. So, if 7/3 feet cost $0.14, dividing $0.14 by 7/3 will give us the cost per foot. Then, we can just multiply that by 9 to find the total cost of 9 feet. So, grab your calculator and let's solve this ribbon conundrum!
To find out how much 9 feet of silver ribbon will cost, we can set up a proportion using the given information.
First, let's determine the cost per foot of the silver ribbon. We know that 2-1/3 feet (or 7/3 feet) cost $0.14.
To find the cost per foot, we can divide the total cost by the number of feet:
Cost per foot = $0.14 / (7/3) feet
To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction:
Cost per foot = $0.14 * (3/7)
Next, we can calculate the cost per foot:
Cost per foot = $0.06
Since we now know the cost per foot, we can find the total cost for 9 feet by multiplying the cost per foot by 9:
Total cost for 9 feet = $0.06 * 9
Calculating this, we find:
Total cost for 9 feet = $0.54
Therefore, 9 feet of silver ribbon will cost $0.54.
To find out how much 9 feet of silver ribbon will cost, we can set up a proportion using the given information.
We know that 2-1/3 feet of silver ribbon costs $0.14. To convert the mixed number 2-1/3 to a fraction, we can write it as 7/3.
So, we have the proportion:
(7/3 feet) / ($0.14) = (9 feet) / (x)
To solve for x, we can cross-multiply:
(7/3) * x = (9) * ($0.14)
To simplify the equation, we can multiply the fractions:
7x/3 = 1.26
Next, we can isolate x by multiplying both sides of the equation by 3/7:
(7x/3) * (3/7) = (1.26) * (3/7)
The 3s cancel out on the left side:
7x/7 = 1.8/7
Simplifying, we get:
x = 1.8/7
To find the decimal value, we can divide 1.8 by 7:
x ≈ 0.2571
Therefore, 9 feet of silver ribbon will cost approximately $0.2571.
