Question

Kiran bought 6 yards of ribbon for $3.90. Which ratio is proportional to 6 yards at $3.90?

Answer 1

To find a proportional ratio to 6 yards of ribbon for $3.90, you calculate the price per yard and then multiply that unit price by the desired number of yards.

So, the correct answer is D.
`\( \frac{\$3.25}{5 \text{ yards}} \)`.

Step-by-step explanation:

Kiran bought 6 yards of ribbon for $3.90.

The ratio of cost to yards is given by:

`\[ \frac{\text{Cost}}{\text{Yards}} = \frac{\$3.90}{6 \text{ yards}} \]`

Now, simplify this ratio:

`\[ \frac{\$3.90}{6 \text{ yards}} = \frac{\$3.90 * (1)/(6)}{6 \text{ yards} * (1)/(6)} \]`

This simplifies to:

`\[ \frac{\$0.65}{1 \text{ yard}} \]`

So, the correct ratio is $0.65 for 1 yard.

Now let's check which of the given choices is proportional to this ratio:

A.
`\( \frac{\$1.36}{2 \text{ yards}} = \frac{\$0.68}{1 \text{ yard}} \)` - Not proportional

B.
`\( \frac{\$1.92}{3 \text{ yards}} = \frac{\$0.64}{1 \text{ yard}} \)` - Not proportional

C.
`\( \frac{\$2.64}{4 \text{ yards}} = \frac{\$0.66}{1 \text{ yard}} \)` - Not proportional

D.
`\( \frac{\$3.25}{5 \text{ yards}} = \frac{\$0.65}{1 \text{ yard}} \)` - Proportional

So, the correct answer is D.
`\( \frac{\$3.25}{5 \text{ yards}} \)`.
