Rosa believes she can ise a division expression to find the cost per pound of ground beef when 2/3 pound sells for $4. Which statement best explains why Rosa is correct or incorrect?

She is correct that she can use a division expression.

It would be  $4/(2/3)  OR 4 ÷ 2/3 = cost per pound.

Not an easy division, but using the rule: invert the divisor and multiply.

4 × 3/2 = 6  So the cost is $6 per pound.

Step-by-step explanation: It would be easier to answer if the statements were included.

Using a decimal equivalent for 2/3,  4/0.667 is an easy division expression to solve on a calculator.

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
