Question

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?

Answer 1

Answer: 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.
