if 2 1/3 feet of silver ribbon cost $.14 how much will 9 feet cost
if 2 1/3 feet of silver ribbon cost $.14 how much will 9 feet cost
surely you can tell that $54 is a totally unreasonable answer.
Always do a sanity check before that final submission.
2 1/3 = 2 + 1 / 3 = 6 / 3 + 1 / 3 = 7 / 3
9 / ( 7 / 3 ) = 9 ∙ 3 / 7 = 27 / 7
$14 ∙ 27 / 7 = $378 / 7 = $54
OR
x = cost of 9 feet ribbon
( 2 1/3 ) / 14 = 9 / x
( 7 / 3 ) / 14 = 9 / x
7 / ( 14 ∙ 3 ) = 9 / x
7 / 42 = 9 / x
Cross multiply.
7 x = 378
x = 378 / 7
x = 54
9 feet ribbon will cost $54.
Well, let's do some math in a humorous way! If 2 1/3 feet of silver ribbon cost a mere $0.14, then we can say that silver ribbon is on a fantastic discount! Now, if we want to find out how much 9 feet of ribbon will cost, we can imagine that the price might sneakily increase because the ribbon realizes it's in high demand. So, we'll need to use a little bit of math here.
If 2 1/3 feet cost $0.14, it means that each foot of ribbon costs $0.14 ÷ 2 1/3. So, let's divide the cost by the length:
$0.14 ÷ 2 1/3 = ???
Oh, dear math gods, this division is slightly complicated. Let me consult my trusty calculator... *beep boop beep boop* Ah, here we go!
$0.14 ÷ 2 1/3 = $0.06 per foot.
Now, to calculate how much 9 feet of ribbon will cost, we'll multiply the cost per foot by the length:
$0.06 × 9 = ???
More math calculations?!?! Oh boy! *calculating intensifies*
$0.06 × 9 = $0.54.
So, my friend, it looks like 9 feet of silver ribbon will cost you a whopping (please insert drumroll) $0.54! But remember, prices can be tricky, so always double-check before making your purchase. Happy ribbon-tastic adventures!
To find out how much 9 feet of silver ribbon will cost, we can use the information given for 2 1/3 feet and apply it proportionally.
First, let's calculate the cost per foot of the silver ribbon. To do this, we need to divide the total cost by the length of the ribbon.
The given cost for 2 1/3 feet of silver ribbon is $0.14.
To convert the mixed number 2 1/3 to an improper fraction, multiply the whole number (2) by the denominator (3) and add the numerator (1). This gives us 7/3.
So, the cost per foot can be calculated as:
$0.14 / (7/3) feet
To divide by a fraction, we multiply by its reciprocal:
$0.14 * (3/7) feet
Now, we have the cost per foot of the silver ribbon, which is $0.06 per foot.
To find out how much 9 feet of silver ribbon will cost, we multiply the cost per foot by the length:
$0.06 * 9 feet = $0.54
Therefore, 9 feet of silver ribbon will cost $0.54.
