Question

Hailey paid $13 dollars for 1 3/7 kg of sliced salami.

Answer 1

Is the question how much it cost per kg?

If so, divide $13 by 1 3/7 kg.

13/(1 3/7) = 13/(10/7) = 13 * 7/10 = 91/10 = 9 1/10

Answer is 9 1/10 dollars per kg.
(Assuming I guessed your question correctly.)

Answer 2

$9.1 per kg of sliced salami.

Explanation:

We are supposed to find unit rate for the given scenario.

Hailey paid $13 dollars for 1 3/7 kg of sliced salami.

To find unit rate, we will divide total price by total weight.

`\text{Unit rate}=\$13/ 1(3)/(7)\text{ kg}`

Convert mixed fraction to improper fraction:

`\text{Unit rate}=\$13/ (10)/(7)\text{ kg}`

Convert to division problem by flipping the fraction as:

`\text{Unit rate}=\$13*(7)/(10)\text{ kg}`

`\text{Unit rate}=\frac{\$13*7}{10\text{ kg}}`

`\text{Unit rate}=\frac{\$91}{10\text{ kg}}`

`\text{Unit rate}=\frac{\$9.1}{\text{ kg}}`

Therefore, unit rate is $9.1 per kg of sliced salami.
